Very surprised this has not been recommended yet. Gintama and FLCL are along the top of my favorite lists for their craziness and randomness.
Sure, we've got different things going on, the arc-based-200(+?) episode, pure comedy Gintama and the more serious, short OVA FLCL, but plot elements aside, watchers will definitely get engrossed in the whackiness nature of both animes.
Highly, highly recommend both not just for their fun, random nature, but their great execution, art, characters, sound, and storyline.
