Good question...

1. Tony Bennett
2. Frank Sinatra
3. Humphrey Bogart
4. Louis Armstrong
5. Dean Martin
6. Sammy Davis Jr.
7. W.C. Fields
8. Steve McQueen
9. Rodney Dangerfield
10. Babe Ruth

I figure all those guys would be fun to hang out with for any type of big party....the women would be there, they just wouldn't be invited to dinner
