A young man goes into a pharmacy and asks the pharmacist "Hello, could you give me condom. My girlfriend has invited me for dinner and I think she is expecting something from me!"

The pharmacist gives him the condom; and  as the young man is going out, he returns and tells him: "Give me  another condom because my girlfriend's sister is very cute too. She always  crosses her legs in a provocative manner when she sees me and I think she  expects something from me too."

The pharmacist gives him a second  condom; and as the boy is leaving he turns back and says: After all, give me  one more condom because my girlfriend's mom is still pretty cute  and when she sees me she always makes allusions...and since she invited me  for dinner, I think she is expecting something from me!!

During dinner, the young man is sitting with his girlfriend on his left, the sister on his right and the mom facing him. When the dad gets there, the boy lowers his head and starts praying: "Dear Lord,bless this dinner...thank you for all you give us...!!!"

A minute later the boy is still praying:  "Thank you Lord for your kindness..."

Ten minutes go on and the boy is  still praying, keeping his head down.  The others look at each other surprised and his girlfriend even more than the others. She gets close to the boy and tells him in his ear: "I didn't know you were so religious!!!"

The boy replies:"I didn't know your dad was the  pharmacist!!!"
