T-Rex: All funny t-shirts use the same unmodified t-shirt canvas:

T-Rex: Slogan on the front! And maybe on the back sometimes!

T-Rex: Forget that, man! Let's kick it up a notch or two! Let's break free of our self-imposed t-shirt boundaries.
Dromiceiomimus: How? Funny sweaters? Funny evening gowns? Funny HOSIERY?
T-Rex: Layers, Dromiceiomimus! SEQUENCES.

T-Rex: Beneath an "I'M WITH STUPID" shirt, wear another one that says "NO, NOT REALLY".
Utahraptor: Handy in case Stupid gets mad!

T-Rex: Exactly! And beneath that, another shirt that says "IF I WAS STANDING NEXT TO A VISIBLE MINORITY WITH THE OTHER SHIRT I DIDN'T MEAN IT AND I APOLOGIZE!!" Beneath that, "YOU GUYS, I'M NOT ACTUALLY RACIST"; beneath that, "IT WAS JUST THE UNFORTUNATE JUXTAPOSITION OF MY SHIRT FROM 4 SHIRTS AGO AND A PERSON"

T-Rex: I was inspired when I saw a racist person stripping!
T-Rex: I thought, wow, if only they'd been wearing the shirts I just invented.
