Plot

Spike plays a prisoner doing 500 years at Sing Song Prison. However, he has come up with an escape plan and starts digging a tunnel under his cell floor using a teaspoon, only temporarily stopping whenever a guard or the warden walks by. 20 years (and 6,500,004,385,632 teaspoons) later, Spike finally digs up through the outside of the prison wall. He returns to his cell to get his disguises but stops all escape activity when the warden comes walking by again. When Spike mentions to the warden it is his 20th anniversary in prison, the warden suddenly remembers it's his wedding anniversary and runs out to get his wife a gift. This prompts Spike to grab his disguises, and run through and out of the tunnel. Finally free, he gets into a train boxcar, where he guts out a television set to hide in it. Seconds later, the TV is hauled onto a truck and taken to Sing Song Prison. As Spike talks about the many places he plans on visiting, he suddenly sees the warden at his desk on the phone and goes into a panic. Turns out that the TV is the anniversary gift for the warden's wife.
