Funny man

The year is 1969, he just got back from Vietnam and had an apartment in Palm Springs. He now 20 and that would make me 12. He is laying on the couch eating a popcycle (root beer I believe) and I am laying on the floor in front of him as were watching TV. A new nation wide commercial for crest toothpaste makes it's debut. You see to girls and the one who is crying says "My boyfriend said my breath could sink a battleship 100 yards away". The other girl says "Is your boyfriend right?" Without missing a beat yo hear my brother say "No, I sunk it from two hundred yards away". I have trouble with my kidneys because I had a belly laugh for 23 straight days. Everyday was like that with him.
