My grade 10 school trip was to the arts festival in Adelaide. One day we ran across a couple of women asking people to try their chocolate covered munchies. A good hand full later somebody asked what they were. 

Chocolate covered SILK WORMS

Now I have to say the munchies were great, but the show after the question was answered was outstanding. 

One teacher fainted, and  three people burped their cookies. Add the numerous people looking greener than Kermit the frog and it made for an interesting moment. 

As for myself, I took the paper cup full offered by one of the women and with a couple of mates of the cast iron stomach variety, munched happily while chaos reigned.
