A woman was sobbing on the side of the street because she had accidentally locked her keys in her car,

a passing soldier saw this and assured her that he can help.

She looks on amazed as he removes his trousers, rolls them into a tight ball and rubs them against the car door.

Magically it opens……. "That's so clever," the woman gasps. "How did you do it?"

"Easy," replies the soldier. "These are my khakis."
