Group of guys decided to tour!

A group of guys decided to tour the brewery where their favorite beer was made, As they marvelled at the process, one of them slipped and fell into a huge vat of beer. Brewery workers tried to save him while his friends waited outside. A half-hour later, the supervisor came out to tell the guys the bad news - their friends had drowned.
"Do you think he suffered much?" one of them asked.
"I don't think so." said the supervisor. "In fact, before he drowned, he climbed out three times to go to the bathroom."
