Yesterday I saw a guy with a bicycle in the subway station in Sörnäinen. He had the bike with him on the escalator, going down. Once he almost lost control of the bike, but caught it before it could fall.
In Rautatientori the guy tried to take the bike up on the escalator among the onlookers' screams "hey, the elevator has been invented". This time he did lose control of it, and another guy caught it falling down. Several "smurfs" showed up and lectured the bicycle man about elevators and about the dangers of taking a bike on an escalator.
When the escalator reached the higher level, the man looked around to see if the smurfs are watching, and took his bike up the next escalator.
