My favorite one was a Pinky & the Brain lunchbox, of the poofy variety. I loooooved that cartoon! Apparently I did a rather silly impression of Pinky when I was a kid... occasionally at family gatherings, someone will still ask me to "do the pinky voice".... mildly embarassing, heh.
On a sidenote... so glad to hear I'm not the only one who was afraid of the lunch line! Guess my social anxiety goes back a long way. Seriously, it terrified me... didn't get over that till my senior year in HS...!
