husband and wife shopping

A husband and wife are doing their grocery shopping.
The man picks up a case of beer and sticks in into the shopping cart.
'What do you think you're doing?' asks the wife.
'They're on sale, only $10.00 for 24 cans', he says.
'Put them back. We can't afford it,' says the wife and they carry on
shopping...
A few aisles later the woman picks up a $20.00 jar of face cream and
sticks it into the cart.
'Whoa, what do you think you're doing?' asks the man.
'It's my face cream. It makes me look beautiful,' she says.
The man replies...

'SO DOES 24 CANS OF BEER, IT'S HALF THE PRICE'!
