Col Henry Blake: "Bet you don't know what kind of wood this is", stroking his new desk.
Hawkeye: "It's oak"
Col Blake: "Nope. It's oak!"
After all these years I still don't know why I think that's funny.
Oh I remember that episode! They traded that sweet desk to some Korean officer in exchange for drugs or something. They cut the back of Blake's office out and lifted the desk away with a helicopter(?)
Remember that episode where everyone was pulling pranks and Hawkeye was paranoid someone was going to prank him and he surrounded himself with barbed wire and at the end you find out he was the only one pranked. Making him paranoid WAS the prank!
ok, that didn't have a line quoted, but there was one episode where Burns dug an air raid shelter and B.J. filled it with water and yelled "AIR RAID" and Burns runs out in a panick and jumps into the shelter.
