Haha! I was thinking the exact same thing. You couldn't help but get the feeling he was having a hard time restraining himself from repeating the joke he made months ago.The main take from yesterday's commentary is that CK acknowledged that Gaudu is not pronounced like Godot, so the Samuel Beckett jokes are out the window. I could have seen that one running for a few seasons.
CK: Who's waiting for Godot, Sean?!
SK: (After a brief pause) Uh, no one's waiting for Godot.
Ok, then! That clears everything up.
