their are so many, the funniest time i think personally was when I just got back too school and I had picked up some dank bubble hash from a festival. It was the middle of the afternoon and the front door was open. Now my friend and I were taking knife hits of the bubble hash and all of sudden in the middle of me ripping smoke out of a plastic bottle from 2 knives the mailman just stares at us while he place the mail in the mailbox, then all of sudden he just smiled and said have a wonderful day. I guess you had to be their to make it funny, anyway i have plenty more but i want to hear other peoples stories
When I was in university we used to steal metal spoons from the University cafeteria and flatten them out and hot knife hash. People made home made bongs out of tin foil and toilet paper rolls. Primitive but it worked.
