That reminds me of one I saw long ago. There was a button on a pole that said "Do Not Push This Button" Rich Hall was the creator of the skit. He walks up, pushes the button and the building behind him implodes.
They filmed it in sequence with a building demolition and their timing was perfect.
He also did another one that was too funny. He was hitch hiking, a car stops and picks him up and when he gets in, the driver was a crash dummy. The scene then went to an overhead and the car hits a wall at high speed. Funny stuff.
