the back who look just like him? Which episode of Family Guy has the clip of an old man driving with kids in the back who look and sound just like him? I think one of the kids say "He's touching my leg." But they all have the same grown man voice so it's funny.
I think it's the one where peter keeps going back in time to the first date with his wife and blowing it... cus he blew it and she married the giggity giggity guy instead.. and all the kids looked like him . it's one of the newer ones
