Good evening, Bobalu...earwax, huh?

[Bobalu]

It’s a Harry Potter reference.
In the films there is a brand of Jelly Beans called Bertie Botts Every Flavor Beans.

Albus Dumbledore takes one and says “In my youth I was unfortunate enough to get a vomit flavored one” then he bites down on it and says.. “Alas, Earwax”
