Sign: ASK PROFESSOR SCIENCE
T-Rex: ...And get an answer from me, because I steal his mail AND I'LL NEVER STOP!
T-Rex: Our next letter comes from Jake!
T-Rex: Jake writes, "What would happen if I had a black hole in my belly?" Well, Jake: you'd die.
Dromiceiomimus: Even Superman would die if he ate a black hole.
T-Rex: I don't care how silver age your Superman is, anyone with a black hole in their belly is dead from having a black hole in their belly.
Utahraptor: But it wouldn't end there!
T-Rex: Of course not!
T-Rex: The black hole would then drop towards the nearest gravity well, which would be the Earth's core, where it'd devour the Earth from the inside out and eventually kill everyone. THEN you'd have a black hole with the mass of the Earth plus the black hole's original mass orbiting where Earth used to be.
T-Rex: So to answer your question, JAKE, you'd become the greatest - and final - mass murderer in Earth's history.
T-Rex: ARE YOU SATISFIED, JAKE?
T-Rex: ARE YOU PLEASED, JAKE, WITH WHAT SCIENCE HATH WROUGHT??
