Though the scene with Sheldon and Leonard in the ball pit on last night's "Big Bang Theory" was hysterical, overall I found the episode to be one of those occasional outings where Sheldon's behavior is pushed so far to the extreme that you wonder why any human being would tolerate him, why Leonard would live with him, the others be friends with him, etc. And I usually find those episodes tough to take, as was the case here. What did everybody else think?
