I've recently started watching the anime version of the bread-baking shounen manga Yakitate!! Japan. The series is pretty good (although some of the jokes feel a little overstretched to me), but my favorite part of the show has become the closing credits, which feature the bakery manager character doing an elaborate disco routine. I watch it every time:
I can't tear my eyes away. The first several episodes of the show don't end with this brilliant sequence, but if you hang in there until episode 11 or so you can watch this to your heart's content.
