Albion and Bosco are right. If we don't get the "jokes", we get a bunch of fodder instead. Yeah, people might be happy to see their favorite fodder get in, but guess what? People love seeing their favorite "jokes" get in - and probably much moreso than the people happy about their fodder since there's a much bigger communal celebration aspect to it.
The "jokes" pretty much also have an infinitely higher chance to do well in the contest. If a fodder character wins a round, they won against fodder that's worse than them. But, well, L-Block, etc, etc, etc
Plus, really, "joke character" is horribly arbitrary. Is Captain Qwark a joke character? What about Doc Louis? Epona? Tingle? It just comes down to Goose choosing who he doesn't want in, as opposed to, you know, having some f***ing user NOMINATIONS.
