I love practical jokes and have pulled off several great ones.
I read about this one a few months ago and still laugh
My most elaborate was building a wall at a friends house while they were on vacation. The wall separated the bedrooms from the rest of the house. It was a real wall. Studs, drywall, mud, paint.
We also had a video camera to record their reaction. It was great.
My wife used to work for the Hong Kong Council of Academic Accreditation which is the organization that accredits university programs and overseas degrees. They also accredit things like beauty and barber colleges.
At the end of one these accreditation exercises, they’d have a buffet/cocktail party and I’d often (Until I pulled this stunt) get to go as the tag-a-long spouse.
For the party for beauty colleges, I made sure my head was shaved and the Van Dyke beard trimmed. Wore an actual suit and a shirt with French cuffs. Before I left work, however; I used some card stock I had for book repair in my library to make about 20 fake business cards using a color laser printer. The cards said: “Code Red Salon Saving Hong Kong’s Hair from High Fashion since 1987” There was a police light logo I swiped from Drudge report and resized. I also included a made-up telephone number and address. When the other attendees asked who I was I gave them the card and explained, “When a woman goes to your salon on Friday and her family and friends laugh at the strange unflattering cut she received from a high dollar salon she comes to me on Monday to salvage her dignity.” The look on their faces was priceless. My wife almost killed me when she found out what I was doing
