Dear Abby, Help I think I upset my uncle

I'm visiting my Uncle Sirius's house. I brought over The Dark Knight trilogy with us because BATMAN!Our enemy Voldemort came by and at first I thought that's what made my uncle mad,then I remembered that when Voldy came by once and stole a jug of pumpkin juice mixed with tequila, my uncle wasn't that upset.This time Voldy came by for just one reason: Batman. Anyways, when good ol' Heath said "why so serious", Voldy bursted out laughing.Then he looked at Sirius and said, "why so Sirius! Get it?"

My uncle snapped, "Why so nosey?" and stormed out of the room.I had no idea why he was so triggered, and I have to admit I was on Voldy's side on this one.Even though he killed my parents and he's kinda a dick, I'm not one for making fun of people for their appearances.I may have tried to blast him to pieces, but I have never gone so low to poke fun at his insecurity of having no nose.That's some petty high school shit right there.

I follow my uncle to confront him, and to my surprise, he was crying.What a touchy old dude! But he opened up to me on how he used to love Batman, but now he can't make one reference to the franchise without some idiot saying "why so Sirius".All his life he'd been made fun of for his name, especially since the invention of Sirius satellite radio, and he was tired of being mocked.He said this to me?How many times have kids called me Hairy Potty, or Harry Pothead?I was once sent to Dumbledore's office because there was a rumor going around that I was selling weed!

My uncle was very offended when I pointed this out and now he won't talk to me.How do I get my uncle to take a friggen joke and not act so 2007 Britney toward me?
