The Moebius, a tribute to Improv Everywhere.
This is best pulled with a group of 6-10 people at the most.
Venue, a busy coffee shop, or smaller area with a captive audience. You need the same group of people for the entirety of the prank.
Scenario: Several agents take their places as customers. Prank begins. Several key events need to happen repeatedly, at 5 minute intervals for a minimum of 1 hour. 12 repetitions.
Time repeats every 5 minutes. Two people enter and stand in line, usually a couple. Break into an argument. One storms out, the other follows calling their name. Event repeats exactly 5 minutes after the initial event began.
Various other agents in various locations also begin to repeat time.
A phone rings every cycle at the same time, the same conversation occurs.
Someone else drops something each cycle. Bends to pick it up. Someone sneezes each cycle.
The point is, none of the agents seem o know each other. If someone asks what's up, you are normal, and you do not realize that time is repeating for you.
This can be assembled and ad-libbed in a short time. Once you have the first repetition down, use it the same each time.
If something steps in and changes for you, such as someone at the door, hold it for them, EACH TIME after that.
