Looking for Crisco

There was this old guy wandering around in a supermarket calling out at intervals:

- Crisco? Crisco? CRIS--CO!!!!

Finally a store clerk approached.

- Sir, the Crisco is on aisle five.

- Oh - replied the old guy - I'm not looking for Crisco, I'm calling my wife.

- Your wife is named Crisco?

- Nah - he answered - I only call her that when we come to the supermarket.

- Oh? What do you call her when you are not in the supermarket?

- Lard Ass!
