Sammi (a man of Afro Caribbean heritage) has been having problems in the 'bedroom' department and his wife is frustrated, she demands Sammi goes to see his GP about the problem.
A few hours later the wife is surprised to see Sammi come home dressed in a 3 piece suit & tie , bowler hat and black shiny shoes, with a briefcase in his hand.
She says to him ''Sammi why is you dressed up like a dog's dinner?''
Sammi replies '' The doctor say I is Impotent !, If I is impotent , I is going to look impotent ''
Reminds me of OH and a spelling list he gave out for his pupils to learn, the Head who was a father of one girl in the class, rang up to ask if he really meant impotent to be on the list.
