Pink Curtains

Thambo entered a store that sells curtains.

He said to the salesman, "I would like to buy a pair of pink curtains."

The salesman said, "Sir, we have a large selection of pink curtains."

He showed Thambo several patterns, but Thambo seemed to be having a hard time choosing.

Finally, he selected a lovely pink floral print.

The salesman asked, "What size of the curtains do you need sir?"

Thambo replied, "Fifteen inches.

"Fifteen inches?" The salesman asked. "That sounds very small, which room are they for?"

Thambo replied, "They are not for a room, they are for my computer."

The surprised salesman replied, "But sir, computers do not have curtains!"

Thambo replied, "My computer has windows!"
