Two men were drunken,but neither one admitted it.

One took out a flashlight and turned on to the roof of the room. So there was a beam of light.

“Hi, buddy, climb on to the top of the pole.” He referred the beam as a “pole”.

“Come on, my dear” He continued “If I were on the top of the pole and you turned off the flashlight, I would fall down to death!”

Based on famous Chinese comic Hou Baolin.
