Back in the late 70's early 80's , I lived in Worcester. A bunch of us hung around including dennis leary's brother "Kiwi".
I remember one time dennis was with us drinking etc . He already was trying to be a commedian and all night he was hitting us with the jokes and one liners. I remember talking about it with my friends on the way home that night. We all concluded that he wasn't very funny and would never make it in show business!!
I guess we were wrong!
