where are your gloves and your helmet?

Hee! Let me see if I can guess the speakers.

1. "Whoo! THat thing kicks like a mule!"
Adam after Ray lets him play with a proton pack.

2. "So we've devised this test to determine what happens in a case of actual total protonic reversal..."
Either Egon or Jamie.

3. "I looked at the trap, Adam!"
Wouldn't that be, "I looked at the trap, Jamie"? Adam's the one who's constantly getting hurt.

4. "With all the flammable stuff you two test out, how do you manage to keep not only your eyebrows, but your facial hair?"
Peter or Winston.

5. "SOMEBODY GET THE BACTINE!"
Definately Peter. ;)
