A husband and wife are shopping in their local Wal-Mart.
The husband picks up a case of Budweiser and puts it in their cart.
'What do you think you're doing?' asks the wife.
'They're on sale, only $10 for 24 cans,' he replies.
'Put them back, we can't afford them,' demands the wife, and so they carry on shopping.
A few aisles further on along the woman picks up a $20 jar of face cream and puts it in the basket.
'What do you think you're doing?' asks the husband.
'It's my face cream. It makes me look sexy and beautiful for you when we're making love,' replies the wife.
Her husband retorts: 'So does 24 cans of Budweiser ... at half the price.'
