Funnyman Al Franken has become a grandfather.

The former Saturday Night Live regular-turned-Minnesota Senator and his wife Franni were celebrating on Thursday (30May13) after their daughter Thomasin gave birth to a little boy.

Franken says, "Franni and I are thrilled that our grandson Joseph Bryson Greenwald was born. He came in at six pounds, 11 ounces. Somehow, in the last few hours, Franni and I have already managed to spoil the baby. Mother and baby are healthy and happy."
