But imagine trying to keep yourself to yourself, while wearing no trousers.
London underground passengers got more than they bargained for today to mark the No Pants Subway Ride 2016.
A ridiculous event originating in the US, trouser-less British fans of the occasion filled tube carriages at the weekend.
It began as a mass prank in 2002 but has now swept the globe and become almost a cult occurrence.
If you want to take part, all you have to do is board a train while wearing nothing on your bottom half.
Seems relatively simply (if not a little nippy this time of year!).
These guidelines have also been published so you can ride the tube the right way.
• Participants are not to take their trousers off on the platform – only on a moving train
• Spread participants out so they're not too densely packed
• Five to six trouserless people per carriage
• No flash photography on the underground
Ben Gerrey, 23, told The Metro: "People don't talk to each other on the tube. But when you've got your trousers off lots of people talk to you, and I like talking to people.
"One time a passenger started to talking to one of my group members and myself, and five minutes later he took his own trousers off. It was brilliant."
