1960s recording studio.
A bald musician walks up to John Lennon.
Bald man: Hey, John. Can I join The Beatles?
John: No chance.
Bald man: Why not?
John: Because we're a fringe group.
Ringo Starr: (who we only now realise is present, on drums) Badumbum Tish!
All 3 men look directly to camera, wink and smile.
