In their sales pitch, the inventors of silly string sprayed their interviewer with an entire can. The inventors were attempting to pitch to the children’s toy giant Wham-O, but the interview went south when they emptied the can of silly string all over the interviewer. The Wham-O representative got incredibly upset and promptly asked the inventors to leave the building. The next day, they received a telegram from Wham-O to send over 24 cans of the stuff for market testing.
