Banta took one of his friend to a punjabi bar. Most of the people sitting there were sardars.Banta being regular customer was greeted by all.
Banta then ordered beer and both were sitting having their beers when someone yelled "21", and there was a small uproar of laughter. A few minutes later someone else yelled "34" and another roar of laughter rose up.
Banta's freind got confused about this, asked Banta "Why is everyone laughing at the numbers being called out"
Banta said, "Well we've been telling the same jokes for so many years that we just numbered them all and if you want to tell a joke you just call out a number"
Banta' friend nodded and said "Can I try?" Banta nodded and his friend called out "121" and everyone in the club roared with laughter and it didn't die down for at least another 15 minutes after.
"Why did everyone laugh so hard at that joke?" Banta's friend asked.
Banta said with a small chuckle, "We haven't heard that one before."
