Who can tell me the name of the song in the following joke?

There is a mental hospital to prevent patients from escaping. Built 100 wall. Only two patients can escape at a time.

They went round and round. When turning to the 30th wall, Patient A said to Patient B, Are you tired? B said: not tired.

They're turning again. They rummaged over and over again. When turning to the 88th wall, A said to B, Are you tired? B said no.

They rummaged over and over again. When turning to the 99 wall, A said to B, Are you tired? B said: tired.

Let's go back to rest. A said, ok!
