Riddle Me This/Riddle Me That

[ulala06]

a man walks into a bar and orders a glass of water. the bartender pulls out a gun and points at him, and the man says thank you and leaves. why?

and this one's just funny so i'm going to post it AND it's answer because there's NO WAY that anyone would get it:

A man goes to a restaurant, orders albatross, takes one bite, leaves the restaurant and shoots himself. Why?

ANSWER: The man was stranded on a desert island with himself, his wife and a stranger. One day, the stranger came to him telling him his wife had been killed by wild animals on the other side of the island. That evening, the stranger made dinner for the man out of an albatross that he had found. After the man was rescued, on suspicion, he went to a restaurant and ordered albatross, tasted it, realized that he had eaten his wife on the island and committed suicide.
