Bruce Lee (who lived next door) and Steve McQueen were both supposed to be at Polanski's house party the night of the Tate murder.
McQueen ended up meeting a Tart at a gas station and was shagging her in the toilet instead pf coming to the party.
Instead of them being there to kick ass the only muscle was in the form of Bruce Lee's hairdresser.
"Is Bruce Lee coming to protect us ?"............no but his hairdresser is here

I always find that funny for some reason.
