Funny stories from our lives.

In this thread, I suggest we share funny stories and pranks from our lives.

I'll start with my own.
The other day, in the store where my beloved works, the display case across from hers was completely cleared out for new merchandise, but the merchandise hadn't arrived yet. As I was passing by, I went in and, with a completely serious face, said, "Natasha, you have an empty display case; you should put some air in it and sell it. Maybe you'll earn enough for a fur coat by New Year's." Natasha, a pretty 18-year-old girl who is used to silly compliments from customers, could easily respond in a fun, teasing way, and that's what I expected. But I was very surprised that she didn't. In the evening, my sweetheart came home and told me that there were now signs on the empty display case advertising air for sale: price, country of origin, the intermediary's phone number (i.e., MINE), etc. I thought I needed to do something, because the fun seemed to have ended with me. So, I made stickers that said, "Container of air, the color of a child's surprise, with a lemon scent. For all questions, contact the manufacturer, Aunt Natasha, Ur. Tankistov 12, tel. 8-*****-****8." I bought a large package of 3-liter cans and put these labels on them. I put them in boxes and put labels on the boxes too, with a request not to tilt them, etc.
A friend of mine works as a driver for a delivery van. I asked him to dress a little more formally. We printed money with the "Smeshariki" characters on it and sealed it in an envelope with the documents. Yesterday, he drove to the store and officially presented the documents to Natasha.
As a result, the whole store was laughing for half an hour. Today, the merchandise arrived!!!
