Bus driver (46): Would you put your head back inside please!
Singing passenger (41): Who – me?
Bus driver: Yes, you!
Singing passenger: Was it sticking out that far?
Bus driver: Yes!
Singing passenger: Sorry mate, didn’t mean to be a nuisance… (half under his breath) …they should install a headmeter…
Later, to new female passenger who has just sat down beside him
Singing passenger: Sorry that you'll be forced to listen to my singing, but apparently because of possible accidents they don’t let me stick my head out of the window to sing out…
