Jellyfish Phobia

Large athletic looking guy with a deep gruff voice says to another similar guy:

"Think about it, jellyfish are so weird. They just float there like this (flails arms around) and they just, they just fuck you up you know? Jellyfish are really scary."

[story ensues]

"And then I just ended up looking like a stupid American tourist wearing a speedo, climbing these rocks so I could avoid the jellyfish."

I heard two girls squealing in my Chem recitation. They look like your typical girlie girls, dressed really well, hair in place, that whole thing. I thought it was just your normal "OMFG I GOT ASKED OUT by ____" conversation. But....then I overheard

"And now we're working on an enzyme to catalyze Diels-Alder reaction!"

SQUEEEE
