Little Johnny, all excited, comes running home one day and tells his dad that he got his first BJ.

Johnny's father, beaming with pride, says: Johnnie, I'm calling all my friends and we're going down to the bar tonight and having a few to celebrate.

In the bar, all of dad's friends are abuzz with the news.  One of them yells:  Johnnie, get up on the bar and tell us about it!

The crowd quiets as Johnnie climbs up on the bar.

Well, Johnnie, how was it? someone yells.

Johnnie says:  Well, it didn't taste that good.
