Joke: How You Know A Drummer’s At Your Door

For our discussion section, we were required to meet up with a fellow student and collect folklore from each other. LA is the person I collected from, PH is myself. Our conversation began like this:

LA: I have jokes, if you want those.
PH: Oh, yeah.
LA: My childhood friend’s dad is this older Jewish punk dude and he had a lot of good jokes.
(pause)
Alright, so I have two drummer jokes which are frequently passed around for people in bands because we love to make jokes about drummers.

Then, the informant told me the first joke which is documented in a different post. Here is the second joke:

LA: Drummer joke number 2: told to me by my friend’s dad, he was also in a punk band in high school.
How do you know when a drummer’s at your door?

PH: How?
LA: ‘Cause the knocking speeds up and he doesn’t know when to come in.
