There was a pop group in the 80's called "Frankie Goes To Hollywood"...they had a song out...words were:
"RELAX...DONT DO IT WHEN U WANT TO SUCK TO IT.RELAX DONT DO ...WHEN U WANT TO COME!.....
Brother gave a talk...obviously hadn't a clue about the words.....He said.."Brothers they say in the song........"Relax ...dont do it...well I say....DO IT!!!!
Needless to say all the young ones burst out laughing...much to the disgust of the congregation!! haha
