Been there, done that (well, without the inappropriate actions :P).I nominate a geordie fursuiter who went on tele and dryhumped my pup...
Bumped into Portillo at Westminster tube station once. This was in 2008 so I'm not sure what business he had therei could have sworn i once saw an ex Tory cabinet minister, clutching a copy of an ancient timetable from the 1860s.
Sounds like a Time Lord. I expect it was probably something he was experimenting with. Probably nothing to be worried about,I see lots of very odd passengers. However the three that stick out the most all have the same thing in common, they are all carrying a large trolley, or one of those trolleys that people use to move large items about.
Firstly a gentleman always used to board trains between Stratford-Upon-Avon and Henley-In-Arden in the early 2000's. He was always most polite but wheeled various strange items around on his trolley. These included a microwave (this appeared many times), what looked like a car engine, and random bits of metal. One day the car engine parts appeared on top of the microwave and tied together with rope.
