Speaking of the "Scofflaw" episode a few posts before, there's a scene where Kramer is in Barney's changing room w/Jerry after he just sold his suit to Banya. When Jerry first pops in, Kramer's tan wallet is tucked halfway in his boxer's waistband on his left. After a quick CU they cut back to that original 2-shot, but the wallet is no longer there.
Any others?
