It's a funning thing about extreme fantasies.
I saw a cartoon where Porky is playing a theatrical agent. A wolf keeps bothering him to demonstrate his act. After 5 minutes of the 6 minute cartoon Porky finally agrees to view the act.
The wolf starts: "First I take this can of gas (petrol for us British)." He drinks the whole can. "Then I eat this dynamite." He eats the stick. "Then I take this Nitrogycerine." He up-ends the small jar. "And finally the lighted match." The obvious explosion occurs.
Porky is very impressed. "Stupendous. Marvelous. You're hired."
The wolf apears through a hole in the floor as a ghost. "Great. But there's only one tiny thing wrong with it."
"Yeah. What?" Asks Porky.
"I can only do it once."
