The This Is SportsCenter ads created from the mid-90s onward are 15 or 30 seconds of sports-related parody, some bordering on comedic genius.
Any ad that featured boxing analyst and anchorman Charley Steiner. To wit:
The ad where ESPN tested their Y2K upgrades... which crashes everything, starting a mass riot throughout the headquarters and ending with a shot of Charley - with warrior makeup, his tie on his head, and carrying an old-style lantern - screaming at the camera "FOLLOW ME! FOLLOW ME TO FREEDOM!"
The ad spoofing blockbuster trades, with ESPN trading with TV show Melrose Place. ESPN gets Andrew Shue, who handles anchoring duties with skill (note: he played college soccer as his athletic creds)... and Melrose gets Charley, who gets cast as the new pool boy.
The ad where a rookie anchorman "flames out" during his first day on the job (spoofing rookie athletes who turn pro too soon).
The ad of the Manning family getting a tour of the office - with Peyton and Eli poking at each other the way bored brothers do. They stop when their old man Archie gives them a silent glare...
Any ad involving mascot abuse.
Except for the one where Steve Irwin wrestles the Florida alligator mascot... it's more sad now than funny.
The mascot for Western Kentucky - basically a red blob - unable to figure out if it uses either the Men's or Women's bathroom. Rich Eisen tells the mascot, "Why don't you use the woods out back?"
The other Big Red ad shows him trying to get a ride with Brad Keselowski, but unable to fit through the opening in Keselowski's car. Keselowski suggests he get a ride with Kevin Negandhi, getting into his minivan a few spaces away.
The ad spoofing rainouts - sprinklers go off above the anchormen, and stage crew cover their desk with a tarp.
Dan Patrick working late sees the power go off. He storms through an empty building down to the generator... where he asks bicyclist Lance Armstrong to keep pedaling on his bike to keep the generator running.
Danica Patrick having her race car towed from Dan Patrick's space. (Then again, the sign does say "Reserved for D. Patrick".)
"Honus Wagner worked for peanuts. Literally worked for peanuts!"
Albert Pujols denying he's a machine... all the while giving the audience a Terminator POV.
Russian hockey player Alex Ovechkin is a spy leafing through ESPN's files.
The Oregon Ducks mascot getting tired working in his cubicle, turns and looks at the real ducks in a nearby pond, and sighs.
Arnold Palmer actually making an Arnold Palmer (iced tea and lemonade, for those who aren't aware) in the ESPN cafeteria. The best part: they Don't Explain the Joke.
Stephen King, longtime Boston Redsox fan, gets in on the action. "No players with telekinetic powers" indeed...
Tim Lincecum trying to record a voicemail message, which ends in the most bizarre Strange Minds Think Alike moment in a commercial ever.
The Stanford Tree listening in as baseball player Jason Heyward explains how bats are made from trees in excruciating detail, with the mascot passing out at the end.
LaDanian Tomlinson having a hard time getting everyone's mail in the right cubicle, due to his ever-present visor in his football helmet.
Jay Harris thinking twice about getting on an elevator with the New Jersey Devils mascot.
Jay: Going up?
*Devil shakes head*
*Jay steps out of elevator*
The Devils and Penguins mascots each messing with the office thermostat to their preferred preference, much to the annoyance of Chris McKendry.
John Anderson turning away coworkers to sit next to him in the cafeteria as he's saving it for Stu Scott. Until Maria Sharapova comes along.
World-famous mascot San Diego Chicken goes about the offices pulling pranks... and later takes off the mask revealing mild-mannered Pete Sampras.
Due to all the knee and ankle injuries around the headquarters (artificial turf has a reputation for increasing on-field injuries), SportsCenter decides to switch to natural turf. Complete with sprinklers and lawn mower running in the background.
David Ortiz (Boston) makes the mistake of fixing Jorge Posada's (Yankees) hat by wearing it... just as the Red Sox mascot walks by and thinks the worst.
In Chris Berman's only appearance in an ad, he explains how every show airing live can lead to anything happening, while (possibly faked) bloopers ranging from Dan Patrick just slamming his head on the desk to someone parachuting into the set air.
John Anderson comments that Scott Van Pelt has been going on a streak of incredible shows, which shows a clip from a SportsCenter segment in which Van Pelt says "And A-Rod exhibits inordinate aptitude in spheriodical aviation!" Sadly, Anderson reveals that Van Pelt was using performance enhancers. We are shown FBI agents searching Van Pelt's cubicle and finding a thesaurus. He tries to flee and is tackled to the ground, shouting "UNHAND ME YOU RAPSCALLION!"
During a 1995 edition, fill-in anchor Steve Levy is reading a story about New England Patriots cornerback Maurice Hurst suing the team for cutting him while injured (an NFL no-no) and he gets to the specific injury and says a term for an erection instead of a "bulging disc". Hilarity Ensues, as Levy struggles to finish the segment (with no help whatsoever from Keith Olbermann).
