We could tell the London Tube had a sense of humor when it inspired a rap, a dating app and a LOL-inducing Twitter account.
But nothing quite sums up the Underground's good nature -- or British humor in general -- like this sign, posted to Reddit on Thursday by user butlertron64:
The Tube is known for having a personality of equal parts silly, sweet and serious. The transit system posted a heartfelt tribute to Robin Williams after the actor's death in August and has inspired plans for an eco-friendly underground bike park.
And according to this recent sign, the Waterloo station gets a little busy in the mornings. The station also apparently tastes like fizzy water.
...and we'll gladly take a sip. Pip pip!
