Heh, I found a somewhat amusing piece of tv trivia out.
Apparently when filming Malcolm in the Middle, the writers discovered that Bryan Cranston was utterly shameless and willing to do pretty much anything they put in the script. So they started a background competition to see who could write something into a script that he wouldn't do. They'd put in things they were sure they'd get rid off when he complained or said he wouldn't do it... but.. each and every script, he'd cheerfully agree and go ahead.
This included learning how to roller-skate over the course of two weeks when they put in that his character had been a roller disco champion and he had to do a dance on skates.
Then reached its peak when the writers group got together as a whole, and purely as a joke asked him how he'd feel being covered in thousands of bees. His casual "Sure" sent them back to the writers room, where they wrote an entire script purely on the basis of getting the one sight gag of his character wearing a suit of living bees because they didn't want to admit it was a joke and they didn't have any script involving it yet.
