Some Plebosaurus-Rexes do commit suicide and even the family members will dance on their overly-wide graves. Life is better this way as scientists like Steven Hawking know their threat on the popularity of others while P-Rexes are in a close proximity. Steven, and millions of others like me, want P-Rexes to be extinct from the planet as they are a large danger to humanity.
Spencer: Don't be a Plebosaurus-Rex, Chris!
Chris: Oh no! A detention! Why!! My life is RUINED!! I'm always licking Mr. Lavender's arse!
Lewis: You're such a Plebosaurus-Rex.
