- I am dying of thirst. Please, give me some water... - begged the Bulgarian
- I have no water, but you can buy a tie! - replied the Jew.

Two hours later, the Bulgarian returned, neither dead nor alive, crawling on all fours, tongue lolling out.
- "Why are you coming back?" asked the Jew.
- I found it, but your father said he wouldn't let me in without a tie...
