Curse of the Wishing Well

Curse of the Wishing Well is a story in Scooby-Doo... Mystery Comics #28

Premise
Money is stolen from a Scottish wishing well used in a telethon.

Synopsis
The gang decides to volunteer for Jackie Jacobs' World Children's Fund Telethon. The money collected is dumped into a genuine Scottish wishing well, which is supposedly cursed by a demon. The money, of course, falls through a trap door in the floor and is collected in the basement.

While Shaggy tries to get Scooby to perform his trained dog act, two thugs -- Munger and Gruber -- prepare to steal the money when it hits $250,000. The two gag and bind a guard in the basement, and Munger emerges from the well wearing a demon suit. Fred, Shaggy and Scooby race down to the basement, but the money has been vacuumed out of the storage room. The guard is able to give a description of their rented getaway van, and Fred, Shaggy and Scooby chase them down in the Mystery Machine.

The two thieves get away, but the stolen money is recovered -- or so it seems. However, when Daphne tries to buy coffee for Jacobs with a twenty dollar bill from the well, the bill turns out to be counterfeit. Scooby and the gang search the T.V. studio from top to bottom and discover the real money in a closet, where the thieves had hoped to retrieve it later when everyone thought the money had been returned and were no longer searching for it.
