Narrator: DOWNSIDES TO BEING A MAMMAL:
T-Rex: Body hair!!
T-Rex: And not just like, on your head!

T-Rex: It's EVERYWHERE.

Dromiceiomimus: Oh, I know. There's a huge secondary market supported ENTIRELY BY MAMMALS in which they pay other mammals to cut the hair off entirely, or to at least attempt to style it, or to pull out the hair, or use special lasers to burn the hair-producing organs in the skin, or to say "screw the lasers" and just ELECTROCUTE THE ORGANS.
Dromiceiomimus: 〚small〛 I find it fascinating

Utahraptor: Are there other downsides?
T-Rex: Oh we haven't even STARTED.

T-Rex: Live birth? Because THAT'S a thing. Plus: better get used to nipples, everyone!
Utahraptor: Well, not EVERYONE. Some mammals don't HAVE nipples, so milk just COMES OUT THROUGH THEIR UNDIFFERENTIATED SKIN.
T-Rex and Utahraptor: AHHHHH

Narrator: DOWNSIDES TO BEING A DINOSAUR:
Off panel: Can't be a dog
T-Rex: Can't ever be a dog, yeah, that's all I've got too
