Diddler on the Roof

Listen here, you smooth-brained simpleton. You thought you were being funny, huh? You, Adolf Nigler, are the kind of person who probably thinks that mayonnaise is a spicy food, and you thought you would post a joke with a reference to some streamer guy, Dr. Disrespect. The humor here lies in the pun of "Fiddler on the Roof" which is a famous musical, and the similar sounding "Diddler on the Roof" which is funny because it sounds a lot like the word "Fiddler". So, you've taken the name of a streamer and then made it into a pun, making it a wordplay.
