Paddy And The Texan
No one answers him and Paddy gets up and walks out. So the Texan sits down to his beer with a smile on his face.
About 30 minutes later the Paddy comes back and walks up to the Texan and asks him "is that offer still good"?
The Texan say "Sure" then jumps up and orders 10 Guinness for Paddy.
Paddy starts knocking them back one after the other all the way down.
As the Texan is standing their counting out the money he asks "I just got to know where did ya go for that 30 minutes you left"?
Paddy looks at him and says "Oh I went to the pub down the road to see if I could do it first".
