Gonard is the source for most of the wackiest jokes due to being a Cloud Cuckoo Lander and to Sean Schemmel's brilliant comedic acting, though YMMV, as it's usually random.
He enjoys his disguise as a Swedish panda zookeeper a bit too much in "The Bracemaster".
"Arugula 4, we have lift-off!"
In "Like Ozu Like Son", the crew is fleeing from a flock of angry birds. When they manage to run into the apartment and they shut the door behind them, Gonard realizes he "forgot his hat". Of course, he goes back into the flock, gets pulverized, rushes back inside the apartment, shuts the door, and then remembers he doesn't wear one. Guano bonks him on the head.
In "The Clip Show", he thinks the gang is going to Finland for their beach vacation, and of course, he never gets it when Lily constantly corrects him. Later, when they're kept late in the studio by Ozu, he laments, "I don't wanna make a clip show! I wanna' go to FINLAND and play SKI BALL and play in the SAND and WIN A TOY SHARK and name it Mister PEACHES!" all in one breath.
"Splashomon" has pretty much the best comedic timing out of any episode.
Characters make jabs at voice-acting in "A Christmas Mikey".
The spirits of Christmas having a change of heart after hearing Ozu's story and teaming up with him to destroy Christmas.
"Reality Bites", the The Real LilyMu reality-show segment.
The American and Buttstonian edited versions of LilyMu in "Uh Oh Guano".
The entirety of the Buttstonian subplot in that episode, but especially this line from the national anthem:
"We are a real country!"
The newscast about Lily's new romance with Mikey, in the form of a Werepuff, in "Night of the Werepuff".
"Script Assassin": Guano quits, and the crew is faced with a replacement writer and director, who is famous for killing off characters in past shows he worked on, and they try to prevent him from killing off Gonard's character at the same time that Ozu is duped into convincing Guano to return. How do they do this? By stalling the shoot as long as possible, and having a dang good time doing it! It's also one of the rare times they are all cooperating with each other 100%!
"Uh, that's my food?" "And it is delicious!" OhSean...
