Radiation Bunnies. My parents were both research scientists, and I spent a lot of time in their respective labs, growing up. It was peak Ninja-Turtles, and Radiation Bunny was a little character I used to draw based on the hazard warnings pasted here and there.

Ms. Barch: Daria, reinforcement?

Daria: Hmmm.. To make a child stop crying, a mother might say; "thats it! I'm sending you to elpaso to live with your REAL father" Whenever the child gets upset the mother might wave an airline ticket in her face or maybe even frame it on the wall by the clown picture. The ticket stops the girl from crying, or showing any emotion. Ever.

Ms. Barch: right thats..

Daria: years later, seeing an airoplane or just hearing one fly over head. Can unleach a pandoras box of represed anger, shattering the grown childs fragile phsyche and triggering a phsychotic and possible deadly episode.
