In an Irish pub, a newcomer ordered a pint of beer. He drank it and complained it was weak. The bartender served him a 10% alcohol beer, and the newcomer said it was still weak.
The next day, the bartender mixed pure alcohol with detergent to make foam and added yellow dye. The newcomer said it was almost good, but still weak.
Annoyed, the bartender mixed sulfuric acid with the alcohol and waited. The newcomer arrived, drank it, his eyes bulged, he paid, and left. He didn’t come back the next day.
The bartender was relieved when he finally reappeared. He offered him a regular strong beer on the house, and the newcomer said:
“No way! I want the one that makes holes in the sidewalk when I piss!”
