For more on "human beans", I'd recommend reference to Roald Dahl's Big Friendly Giant (BFG). Especially if you have kids.
'As I am saying', said the Giant,'all human beans is having different flavors.Human beans from Panama is tating very strong of hats.'
'Why hats?' Sophie said.
'You is not very clever,'theGiant said, moving his great ears in and out. 'I thought all human beans is full of brains, but your head is emptierthan a bundongle.'
'Do you like vegetables?' Sophie asked. hoping to steer the conversation towards a slightly less dangerous type of food.
'You is trying to change the subject,' the Giant said sternly. 'We is having an interesting babblement about the human bean. The human bean is not a vegetable.' 'Oh, but the bean is a vegetable.' 'Not the human bean,' the Giant said. 'The human bean has two legs and a vegetable has no legs at all.'
