Jackie Bright was born in 1919 and died in 2006. He played Gavin the janitor in the Friends episode The One With The Birth and later played Mr. Weinberg in The One With Barry and Mindy's Wedding. He also appeared in the spin-off Joey playing an old man.
Jackie also appeared in Veronica's Closet (1997) and in Dream On (1992) as Uncle Hy. (There is possibly a joke on this in The One Where Old Yeller Dies as when Rachel says Ben said "hi", Ross said "what the word hi?" Rachel replies "no my Uncle Hi".)
