This is a good thread.
I like almost all the dumb holodeck episodes. For some reason, I enjoy the sight of my favorite characters in totally incongruous surroundings and situations.
I also must confess to loving DS9's "Body Parts". I know it's cheesy; especially the ridiculous heartwarming ending where everyone rallies around Quark. But the idea of Quark hiring Garak to kill him is just so hilarious. And when Quark is moving stealthily through his quarters, just waiting for Garak to spring out and murder him, is a great bit of physical comedy.
