Talking about Jackie Mason and Barry Pearl.....
They both appeared in an infamous Broadway play: A Teaspoon Every Four Hours
From Wikapedia
A Teaspoon Every Four Hours is a comedy play written by Jackie Mason and Mike Mortman which was produced on Broadway in 1969.[1] The play set a Broadway record by having 97 previews before its official opening. After its official opening, A Teaspoon Every Four Hours closed after only one performance.
Nat Weiss (played by Mason himself in the Broadway production) is a Jewish widower who learns that his son (Barry Pearl) is in love with a black woman. Eventually Nat himself falls in love with the woman's mother. The play's title is not explained in the play itself.
Mason was interviewed in 2011 about the prospects of Spider-Man: Turn Off the Dark breaking his play's record for most previews. "The longest preview period, I don't see as an honor," he said. "Running a show after it opens, I see as an honor." Mason said that when the record is broken, "I won't cry a tear, because there's nothing to be excited about."
