I pity the fool!

Today is my birthday.  I'm 33 years old.  I have been a fan of Mr. T for a long time.  Rocky III and the A-Team - I mean, come on!  He's awesome!  And I'm lucky enough to share a birthday with him.  And Notorious B.I.G.

Mr. T is 60 years old today.  Notorious B.I.G. would have been 40 today.

Does it mean something that neither of these guys go by their given name?  Mr. T's real name is Laurence Tureaud.  And Notorious B.I.G.'s real name was Christopher Wallace.

Which D-list celebrity do share a birthday with?
