1 Prof. Jones: Look, a man selling mummies! We should buy one for the dining room. What do you think?
2 Monty: Those belong in a museum, dad!
3 Monty: {to mummy vendor} What are you doing with these archaeologically important mummies?
4 Mummy vendor: Promise you'll keep it under wraps?

There are indeed LEGO mummy figures, but alas I don't have any. So I had to make do with what I could find around the house.

At first I was stumped at what to use to simulate a mummy. I figured they would like whitish, so I thought at first maybe a cotton ball? Then I raided the medicine cabinet in the bathroom and found some quilted cotton make-up removers that my wife uses. I just had to cut them to size and roll them up and they would make acceptable—

Wait a minute! There's a pack of gauze bandage!

After facepalming myself I simulated the bandage-wrapped mummies using bandages.
