A good sample of Ween songs?

I'm doing a presentation tomorrow on Ween for my Music Appreciation Class, and while the background info on the band is easy enough to talk about, what I've been debating is what songs to show off. Most other students so far have just shown off a song or two to give an example of their chosen artist's sound, but with Ween they're so all over the place that I'm not really sure what to choose. Does anyone have any suggestions for maybe a few songs that I can use to show off their musical range and style? I'd probably only be able to show snippets of each, although I'm also considering doing a big mash-up sampler of several songs in one 2-3 min track. Thanks in advance!
