I haven't seen all of Season 2 yet, but some of my favourite Season 1 Sheldon quotes are:[when he has just defeated Leonard at 3D chess] "It must be difficult to suck on so many different levels."[from The Pork Chop Interdimencey] "Here--eat this cheese without farting and you can sleep with my sister." AND "If anybody wants to get at Missy's fallopian tubes they are going to have to go through me first."[after bringing Leaonard a hot cup of tea for comfort] "There there."There are so many other great lines, but these are just a few that I still laugh at so hard I start to tear. Amazing show and an even more amazing actor.
