I've always been curious how many takes it took to break that window on that TV episode?..
I can see their first attempt where they said let's just drop it off the stand and give it a little nudge and tie a string to the leg or something and it fell off and bounced across the floor lol then they're like let's throw a brick at it just out of the cameras view and when it bounced off they're like crap and someone pulls out of 45...
