Well, I knew somebody was short in spades.

Well, I knew somebody was short in spades.

You'd have to
1. Know bridge
2. Know bridge on line
3. Know bridge online chat
4. Know how funny it would be if a chat on a bridge table said:
Well I knew somebody was short in spades. (at the end of a very tough hand)
Followed immediately by the expression (by the same player)
Well I knew somebody was short in spades. (at the beginning of the next tough hand)

Anyway, either you do understand all that and are now ROFLYFAO or not.
