Sticky Bike

The other day something unexplainable happened to my bike. I was coming home after a day out. I exited the line 4 metro and sauntered up to where I'd locked it. At this point I noticed something: my whole seat was covered in some sort of stickiness. Tiny dots of dried stickiness which I noticed covered the whole bike. I got out a wet wipe and tried to rid my ride of the mystery stuff with some success. When I got home, my shoe soles were sticky from the pedals. I was mildly annoyed, but more than that I thought how strange this was. What the heck is on my bike? Seriously, what? Did someone come through spraying everything in sight with sprite? Some sort of liquid manna? It's almost infuriatingly bazaar, but this is one of those occurrences that happens in a foreign country.

Since it was clear that I would probably never figure it out, my roommate and I made up a song. I think you'll know the tune:

Sticky bike. Sticky bike.
What did they spray on you?
Sticky bike. Sticky bike.
It's not your fault.
It's not your fault.
