Sorry if this doesn't offend anyone!
A leprechaun and his friend walked into a bar one evening and began ordering pitchers of beer. After a few pitchers, the leprechaun looked around and saw a very large, mean-looking Harley Dude

sitting at the end of the bar. With a smile, the leprechaun ran to the end of the bar and stood in front of this guy. He laughed hysterically, stuck out his tongue and spit all over the mean-looking biker. Looking meaner and madder than ever, the biker reached out to grab the obnoxious little leprechaun, only to miss him as the leprechaun jumped up and ran back to his seat next to his friend.
''If you know what's good for you, don't come near me again or I'll rip off your little green tallywagger!''

yelled the mean-looking biker

.
The leprechaun snickered and started on another pitcher of beer, while his friend told him he thought it would be better not to harass this dude again. A few pitchers of beer later, the leprechaun was beginning to feel pretty intoxicated and fun-loving. Once again, he looked down at the end of the bar and saw the same mean-looking biker

sitting there. The leprechaun chuckled, ran to the end of the bar to stand in front of the same man, began laughing hysterically, stuck out his tongue and spit all over him again. The angry biker

reached out to grab the drunk little leprechaun and was successful in capturing him.
''All right, I've got you this time. I warned you before that if you came near me again I would rip off your little green tallywagger

and that is what I intend to do!''
The leprechaun laughed again and said, ''You can't do that!''
''Why not?'' asked the angry biker

.
''Because,'' giggled the leprechaun, ''Leprechauns don't have little green tallywaggers!''

''Whadda ya mean you don't have a little green tallywagger?''

growled the angry biker

, ''How in the hell do ya pee?''
''Just like this!'' laughed the leprechaun as he stuck out his tongue and spit with all his might.
