A husband and wife are shopping in their local Wal-Mart's and the husband picks up a case of Budweiser and puts it in their trolley.
'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 trolley.
'What do you think you're doing?' asks the husband.
