Two things I learned as a young man. Irish jokes are really funny... except when you tell them to Irishmen.

I learned this after stupidly telling a joke about an Irish potato and a six pack of Guinness one night at a rowdy inner-city party while surrounded by drunken Irishmen.
I was a big, tough, martial arts trained adult male in those days with a reputation as a dangerous street fighter but I guess those micks hadn't gotten the news for I was lucky to make it out of there in one piece.
In the end, after throwing everything I had plus the kitchen sink at them, I kicked the guy in front of me square in the nads so hard he doubled over and jumped the back yard fence and ran for my ride and got the out of there.
I had to stop by the ER because one of them monsters had managed to land one that split my lower lip so bad my lower teeth were actually sticking thru it. At least they didn't bite off my nose or an ear. Nothing stitches didn't fix. Lol.
That was really stupid though for me to tell such a joke to a room full of rowdy drunken inner-city Irish young men. They were not amused.
