Thankfully that premise is the only stupid thing about it. In theory Bob Saget has had those kids sitting on that couch telling them the story of the five years leading up to the meeting of said mother. The rest of it is golden.

Two and a Half Men sucks beyond belief, but the it's a toss up on the other two from week to week. Sometimes BBT scores the win (Sheldon going nuts over getting a napkin that may contain some of Leonard Nimoy's saliva) while other times it's HIMYM (the suit musical number was legen-wait for it-dary.)
Sheldon is awesome. Kaley Cuoco is hot.
