- Every Thursday at 8:40am, it's your chance to take part in the John DeBella Show's 'Grover Knows' feature. Here's how it works…3 listeners will get the opportunity to tell a joke on-air. When telling the joke, the listener leaves out the punchline to see if they can stump Grover or if he can prove that he 'knows' the joke.
To get the chance to read your joke on-air, listen on Thursday morning between 6am and 8:35a for the DeBella Show to tell listeners to call 215-263-WMGK (9645) with their 'Grover Knows' joke.
If you are picked to read your joke on-air, regardless of whether you stump Grover or not, you'll receive this week's prize :
a copy of the book “Neil Young - The Definitive History”
