Comedy Microphone by Richard Griffin (3482)

Magician approaches the microphone
to speak, but it does not work. He looks to the sound guy and as he does
the top of the microphone pops off, he picks it up and places it back
on the microphone. It pops off again surprising the magician. He picks
it up again and places it back, this time it pops off into his face.
Placing the top on again, he looks for a switch to turn the microphone
on, as he does the microphone explodes sending a flash of fire and
sparks into the air.

A great comedy gag for comedy magicians, comperes and children’s magicians.
