You might want to Google image search "Excelsior tank", I've seen that as an image macro before.
That's first thing I thought about as well. Also you might want to Google image search "don't worry guys internet is here". Which is almost same thing in fact.
Reminds me of Metal Slug X co-op on the train stage. At one point, there's an airplane and a tank, and the player in the tank can actually jump on top of the jet and ride it as the other player flies around. Good times.
