One of the oldest jokes I know from my childhood

[Translated from dutch, so there might be some spelling errors]

A man walks in a bar and sees a big jar with money. He asks the barkeeper "what is the jar for?". The barkeeper says "If you put 5 dollar in the jar, I will give you three challenges, if you complete all three challenges you will get the entire jar!". The man is a bit courageous so he puts 5 dollars in the jar. The barkeeper says "great, these are the three challenges; first you have to chug this entire bottle of wodka, if you move a muscle or can't keep it in you lose. If you've done that, you've to pull a tooth from a big bulldog with a toothache outside. And your last challenge is to have sex with the old lady upstairs. She is old and has never had sex in her entire life so you have to give her that pleasure."

So the man takes the bottle of wodka and chugs the entire bottle as if it's water. After that the man is pretty drunk and stumbles outside to the bulldog. The barkeeper hears a lot of noise and a lot of barking and yapping. After 5 minutes the man walks back in and says "I've done it, now where is that old lady with the toothache?".
