Comedy Funnell - The performer who features comedy magic in their routine must have a COMEDY FUNNEL.

Many, many routines are possible with the Comedy Funnel, You request a member of the audience to assist you. The assistant drinks a glass of liquid such as milk, soda pop or water. Now the fun begins-the performer picks up the Comedy Funnel and places it under the assistant's bent elbow. A second assistant is requested to assist in the pumping of the spectator's arm up and down. It is an hilarious sight. Suddenly - the liquid starts to spurt from the funnel into a glass held by the performer, the flow now starts and stops. It gets funnier and funnier-OR-you can pour milk in a child's ear, (using a Magic Milk Pitcher) or make a hole in his elbow, (using a Comedy Fake Ice Pick) then proceed with pumping the fluid from his elbow.

The Comedy Funnel combines all the best ingredients, mystery, magic, comedy, entertainment and audience participation. A winning combination!
