James from Bowling King is a former champion bowler with incredibly formidable skills. Not that his protege Shautieh could tell after spending an entire morning of shopping with him; all James seems to care about is his wife, and he rarely focuses on what he's actually supposed to be doing... but he still manages to see patterns and method to Shautieh's approach that even he wasn't aware of before.
As various deconstructions and parodies have shown, virtually all superheroes are Bunny Ears Lawyers (more so during The Golden Age of Comic Books). Seriously, dressing up in bright colors and knocking people around can only be accepted when you're really good at what you do.
Famed reporter Clark Kent, aka Superman, has a horrible attendance problem. Tolerated, because he brings in the good stories anyway, and one of the reasons Clark chose 'reporter' as a job in the first place was flexible hours. It doesn't hurt that Clark happens to be the fastest typist on staff.
In one story, Superman assumes the identity of Johnny Clark, a firefighter. His taciturn standoffish nature is tolerated by the Metropolis Fire Brigade because he's just that good at saving people. The fact that this new identity allows him to help people 24/7 could also mean the Johnny Clark persona is a Bunny Ears Lawyer for Superman as well.
Peter Parker is probably similar, and likely wouldn't have a job at the Bugle at all were it not for his ability to nab so many photos of Spider-Man. Though for a lot of his career, Peter was freelance.
Even Spidey himself is a Bunny Ears Lawyer amongst the superheroes. He's known as being goofy and weird on top of being a Huge Smart Ass but most heroes consider him a brave, versatile and valuable asset amongst the numerous street levelers, being the Main Hero of New York Streets helps also he's a lot smarter and possibly the most teamed up hero in the Marvel U of his power level.
Before he became Electro, Max Dillon was so greedy he wouldn't do anything unless he was paid. He only saved the life of a coworker after being offered a large bonus. He was only tolerated because he was the best pole man in New York.
She-Hulk is sometimes a literal case. (And often works for a Bunny-Eared Law Firm.)
Deadpool could very easily fit into this category as, despite his blatant insanity, tendency to annoy others and, occasionally, sheer stupidity he is frequently hired as he's just too good at his job.
Hilariously, unlike the description given above, he actually isAx-Crazy...which makes him a whole lot of fun.
He also strays into Crazy Awesome sometimes; for example, when he fights with absolutely no semblance of sense, not even deciding what an attack is going to be until it connects, to beat the Taskmaster.
However, Taskmaster himself called Deadpool out for this, telling him that one of the reasons he's not taken seriously and doesn't make nearly as much money as he could is because he's so crazy that it's even more crazy for people to think they can rely on him. Hell, in some of his earliest incarnations, he would change sides in the middle of a fight if he was offered more money. If you have a hopeless suicide mission, call Deadpool. If you need subtlety and discretion, stay light-years away from him. Also, since Deadpool has developed a conscience and tries to do the right thing, there's no guarantee that he won't turn on someone who just paid him if he thinks the situation warrants it.
Raptor in G.I. Joe comics. Cobra's accountant, he's a Mad FALCONER who dresses like a bird at all times and is regarded as a complete nutjob even by other Cobra operatives and Cobra Commander himself. On the other hand... he's an okay accountant and nobody else would work for Cobra.
Transmetropolitan's Spider Jerusalem is a drug addict, a sociopath, a pervert, a world class cynic who despises his own audience...and a damn fine journalist.
Blue Beetle: Ted Kord is an immature nerd who never stops telling stupid jokes, dresses like a kid's show host, has a disorganized lab and a congenital heart defect. He's also a technological genius, expert fighter and detective who uncovered a conspiracy even Batman missed and died trying to stop it.
Dark Reign: Made Men is a one-shot made up entirely of stories about Norman Osborn and HAMMER making deals with guys like this. Bringing them back to life, getting them out of prison, that sort of thing. Spymaster is a peerless industrial spy and thief... and a con artist who is practically afraid of truth. Attuma is a fearsome and powerful warrior... and a rage case who doesn't understand anything but conflict. The Gamma Corps are an elite fighting squadron of Gamma-enhanced soldiers... and extremely misguided crusaders with a warped sense of justice.
Arthur on The Tick is a perfectly normal everyday human and an experienced chartered accountant in an accountancy firm... Who also wears a full-body moth suit. Even to work. In an aversion, this gets him fired in all continuities.
Arthur: I'm fired? Is there a problem with my work? Mr. Wiederspan: No, no, no, no, no. It's just... Um... IT'S THAT STUPID BUNNY OUTFIT!
The Tick, meanwhile, is trusted by his community as a superhero and protector of the innocent (and not, say, carted off to the nearest insane asylum) in spite of his... Eccentricities. This was actually averted in the comics continuity, in which The Tick started out as an asylum inmate before escaping and becoming a superhero.
Tintin gives us Professor Cuthbert Calculus. He's prone to mishear every single word being said to him due to his hearing impairments and he's a borderline Mad Scientist. However, he so brilliant that he kept getting hired by various groups and governments to design various inventions or to help their science programs.
Professor Calculus was actually the latest in a list of kooky scientists, who apparently held considerable respect in their fields despite their silly behavior (key of which has to Professor Phostle, who discovers a meteorite is apparently going to smash into Earth and can only think of the fame he'll get as its discoverer). He was such a Bunny-Ears Lawyer, however, that he broke out and became a regular part of the cast.
Gaius Julius Caesar in Astérix is irritatingly pretentious, has various odd traits and is weirdly fixated on conquering a tiny piece of valueless territory belonging to a bunch of losers and madmen, who he is nonetheless Friendly Enemies with. He's also one of the greatest military leaders ever to live and by far the cleverest, noblest Roman we're ever introduced to. Cleopatra was also like this - an excellent queen but also a materialistic spoiled brat who eats disgusting food - but she mellows out as the series progresses.
In Paperinik New Adventures there is an actual lawyer, Eugene Photomas, that constantly forgets dates, places, and names (even his own, at one point). However when he is in a courtroom his competence switch is flipped, to the point to be considered one of the best lawyers of XXIII century.
Jughead Jones of Archie Comics fame is sometimes portrayed as this, though it Depends On The Writer. One issue even had Mr. Weatherbee and Ms. Grundy furious at the revelation that Jughead was getting straight-As despite being such an oddball and slacker, and utterly refused to believe it was due to anything other than cheating until he aced a pop quiz.
Mr. Weatherbee Let's just face facts. His mind is a steel trap. Whatever he hears he never forgets; he just files it away until it's needed. He's a sloppy, unkempt, irritating genius.
He even intentionally got himself sent to detention so he'd have a quiet place to study, it never occurred to him to just ask if he could stay after class.
Alexander Glushko of Top 10 is a darker take on the trope, since his bunny-ears are rampant alcoholism. However, since he is the only telepath the Neopolis PD has access to, they're willing to overlook him being black-out drunk on the job as long as he is capable of telling interrogators what suspects are thinking.
