Anytime you hear old people explain anything you know it's going to be hilarious.

Especially when they are explaining something they know nothing about.Check out this video, as these grandmothers try to figure out the meaning, of 4/20.

The video takes a turn from funny to hilarious when these 'grandmothers'  try to figure out what is a 'Bong', then how to actually use a bong/

I found this funny because you can tell this is genuine.

Is this funny to you or offensive?
