If you can't think of anything nice to say, come sit here beside me.
If you can't say anything good about someone, sit right here by me.
Never trust a man who combs his hair straight from his left armpit.
If you can't say something nice about someone, come and sit right here next to me.
He looks as though he's been weaned on a pickle.
If YOU DON'T HAVE ANYTHING NICE TO SAY ABOUT ANYONE..COME SIT BY ME.
