Aardvark For Sale

A man wanted a new aardvark so he looked through the classified ads. He phoned a number he found and an elderly lady answered.

- How much are your aardvarks? - he asked.

- They're L6 each - came the reply.

- Did you raise them yourself? - inquired the man.

- Oh yes - she said.

- Yesterday they were only L5 each.
