More specifically, a remake (https://podcasts.apple.com/id/podcast/cheers-cast-4-14-suspicion/id1403495561?i=1000537064419) of sorts of The Dick Van Dyke Show episode "Impractical Joke (http://dickvandykeshow.blogspot.com/2011/07/episode-109-impractical-joke.html)". There's four basic elements:

Diane pranks the gang; Buddy pranks Rob

Diane/Buddy get paranoid about retaliation

Woody offers Diane a muffin; Rob offers Buddy a doughnut. But they both miss out on the pastry because they think it's been booby trapped in retaliation

Diane/Buddy make fools of themselves by thinking a third party they encounter was sent by the gang/Rob to exact vengeance
