Waterloo

Dvar Torah #2 for Chayei Sarah below reminds be of the following old groaner:

A man goes into a bar very thirsty. He sits down waiting for the bartender to see him. The man next to him calls for the bartender saying, "I'll have another waterloo."

The bartender gives him a tall, ice-cold drink, then asks the newcomer what he would like to drink. Wanting to try this new drink he says, "I'll have a waterloo too.'"

The bartender gives him a tall, ice-cold drink. He takes a big drink and says "HEY! This isn't any good. It tastes just like water ! "

The man next to him looks at the bartender and says, "Well, it IS water...right Lou?"
