"Magical Sledgehammer" joke

A magician was on stage doing his act, when he called for a volunteer from
the audience. A man volunteered and went up on stage. The magician told him
to pick up the 16 pound sledgehammer that was on stage next to a cement
block and break the block apart with the sledgehammer so the audience would
know the sledgehammer was real.

So, the man swung the sledgehammer with all his might and shattered the
cement block. The magician now told the man to hit him square in the face
with the sledgehammer.

Horrified, the man said, "No way. It'll probably kill you".

The magician insisted that the man hit him in the face, saying, "I'll be
fine. I promise you. Go ahead."

"Well,", the man replied, "Ok, here goes."

Again, the man swung the sledgehammer and aimed it at the magician's face.
The result was very bloody. The magician's nose was crushed, teeth fell
out and blood everywhere. After 6 months in a coma in the hospital, the
magician was lying in the hospital bed. One eye opened, the fingers flexed
a bit, the other eye opened, and the magician sat straight up and said,
"Ta-da!"
