one of the funniest back and forths with the guys was this:
leonard asks 'so craig, what do you do for a living?'
craig replies 'i host the late late show with craig ferguson.'
'i see. and what time is that on?'
sheldon then asks 'given that am stands for anti meridian, wouldnt it more logically be called 'the early early show with craig ferguson'?'
'i dont know' craig answers
'the answer is yes. minus eight points'
'i didnt know there was going be a test!' craig exclaims
leonard chimes in 'then you're really not going to like the physical...'
