Squirrel Exterminator sounds pretty funny. What would make it funnier in my opinion would be if the character was doing a dance while standing up or if his legs and arms twitched briefly every 15 seconds or something like that, because in my opinion the character was too simple to look at until the end. If the character's arms moved it would help understand what he's saying and it would make it even more disturbing. A background would help the cartoon too, if the guy was in his basement full of pizza boxes, or if he was near the playground behind the bushes, etc. That would help the viewers understand this guy is pretty weird or crazy. And this cartoon needs an interesting ending in my opinion, maybe show the guy fighting a human sized squirrel? Anyway, hope this helps you and hope it wasn't all over the place.
