The only moments I can think of that were funny that haven't been mentioned (the ones that have had me cracking up all over again):
After Clark burns the heel off Lois's shoe Dean does this weird flailing arms thing that cracks me up every time.
For some reason, when Sperman gets hit with Red K and Lois is exasperated b/c he lets Perry be kidnapped, when he says "Lois don't have a stroke," I just crack up
And I thought Lois' island freak out was pretty funny. (whenever she babbles or doesn't get her way is pretty funny actually)
