Clockwise from Top Left:
A grown man dressed as a baby, running a marathon.
A tree, being chased by an orangutan with an ax, running a marathon.
A man running a marathon in his silk boxers.
A 60 something gentleman, on a motorcycle that is airbrushed with a castle in the clouds, wearing leather pants and a helmet with a woman airbrushed on it, blaring George Michael from his stereo, leading the marathon.
