I don't know if they should have guest appearances left and right... but I'd love it if Weird Al was in an episode. Considering they got John de Lancie... well, that's a good sign that they'd get good geek stars.
So I was looking at this and I said " Omg! Dawson! (my BF) There's people out there that love Weird al and MLP!" He said "Lemme see." I showed him and he said "You drew that." When I told him I did'nt he said " It's scary that there's other people like you out there." Then he smiled and left. Lol
