The Thermos

Cletus goes to work and sees that one of his co-workers has a thermos.
He asks him what it does, and the co-worker responds, “Itkeeps hot things hot and cold things cold.”
Cletus is amazed, and when he gets home, he immediately goesout and buys one. The next day he goes to work and is proudthat he has this wonderful object.
The same co-worker realizes he has a thermos and says, ”What do you have in it?”

He says, “Soup and ice cream!”
