Of course since I am 100% Mick, would not want the other ethnic groups here to think I am being inequitable regarding ethnic humor, so here is an Irish Joke:
God bless the Irish.
As only the Irish can tell a story!
Paddy had long heard the stories of an amazing family tradition
It seems that his father, grandfather and great-grandfather had all
been able to walk on water on their 18th birthday.On that special
day, they'd each walked across the lake to the pub on the far side
for their first legal drink.
*So when Paddy's 18th birthday came around, he and his pal Mick,
took a boat out to the middle of the lake, Paddy, stepped out of the
boat ...and nearly drowned! Mick just barely managed to pull him to
safety. Furious and confused, Paddy went to see his grandmother.
"Grandma," he asked, "Tis me 18th birthday, so why can't I walk
across the lake like me father, his father and his father before him?"
Granny looked deeply into Paddy's, troubled blue eyes and said,
"Because ye father, ye grandfather and ye great-grandfather were all
born in December, when the lake is frozen, and ye were born in
August, ya fookin idiot!
