T-Rex: One day everyone woke up to discover that the force holding atomic nuclei together had decreased slightly, from a strength of 0.007 to 0.006.

T-Rex: This was very disappointing for a lot of reasons!

T-Rex: Not the least of which was the fact that suddenly changing this universal constant irrevocably altered both physics AND chemistry. No elements more complex than hydrogen could form. People's heads fell apart and/or exploded. Life across the entire universe ended in seconds.
Dromiceiomimus: A chilling tale, warning us all of the dangers of altering nucleonic binding force constants!!

Utahraptor: T-Rex, what the heck are you doing?!
T-Rex: Talkin', walkin', little bit of stompin'?

Utahraptor: NO, you're revealing our universe's GREATEST WEAKNESS!! Now EVERYONE knows our one vulnerability!
T-Rex: Hah! Dude, it's not just ONE. Adjust our gravitational constant and we'll ALL be crushed or fly apart.
Utahraptor: STOP REVEALING THE UNIVERSE'S WEAK SPOTS!!

Narrator: LATER: ALTERING UNIVERSAL CONSTANTS IS TOO HARD FOR ANYONE TO ACCOMPLISH
T-Rex: Phew!
Narrator: ...SO FAR.
T-Rex: ...
T-Rex: Whatever, I've had a good run
