Oh wow... I remember this one... My that was long ago. So long ago.

A memory.

Nothing.

Nothing but a...

Memory.

I can't tell if you were referring to the profiles name or you had a sudden existential crisis.

Baby, "Existential Crisis" is my middle name.

Two words for your middle name? Is it joint? Grandpa Existential and Grandma Crisis doing alright?
Following the theme of middle name jokes, my favourite will always be Sonic's middle name.
Sonic: "Speed's my middle name!"
Knuckles: "Really? I always thought it was The"
Sonic Boom has some good ringers on rare occasions.

Actually. sometimes Sonic Boom is pretty funny. The Chrischan omage, and "Knuckles' take on Feminism" were a couple good bits.

Or the episodes with Shadow showing up Eggman. Absolute riot whenever Shadow's on screen. It's like inviting someone on a kids talk show whose well known for swearing and being in R Rated (or 18) movies and they're forced to put up with the childish antics as well as restrain themselves from making a scene in front of the kids.
Same goes for Metal Sonic for me. Personal fave character tbh
