This video is the absolute definition of "don't try this at home".

Armed with nothing more than a GoPro and a borderline-reckless appetite for danger, urban explorer and YouTuber DyingLlama hitches a ride on a double-decker London bus in the most literal way possible.

After speeding around central London for awhile and waving to the occasional bemused pedestrian, DyingLlama climbs down and runs gleefully off into the night.
