Here’s a well thought out bit done by Drex and Maney, KISS 95.1, Charlotte back around Mother’s Day. This is called “Messin’ with Mom” where listeners called their moms to have fun with them. Two things of note in how this was constructed: first they had Cassidy, the female on the show, call her mom so the audience would get the bit. They could have told the audience how it was going to go, but they demonstrated it (and did character development in the process). Then, just before they did it with the listener, they explained the entire scenario of what she’d say to her mom so the audience could get focused just on the mom’s reaction.
