Let's do it at Sigma Delta.

You and David sit silently and ponder your predicament: how to test the **** without using the lab or the university finding out. The task doesn't seem so difficult, as it wouldn't be that compliated to get someone somewhere and ask him if he wants some water. Then all you'd have to do is spike his drink.

"We'll invite someone for the study, pay him $50, and then we have our experiment," you add.
"Yes, but couldn't that be troublesome?" asks David, "The study would move along too slowly that way, and besides, I don't think anyone's going to agree to an experiment in which we won't tell em what's supposed to happen.

"We do it secretly, then. No experiment, no lab, just a natural environment." This would probably mean spiking your own friends' drinks. Are you really so low?

"Okay, but that would mean experimenting on people we know. I don't know about that..." David replies. Apparently -he isn't- that low.

"I've got it!" David looks at you and raises his eyebrows. "Delta Sigma! We'll wait for the next party. That'll be a target-rich environment if there ever was one." There would be plenty of indiscriminate drinking, plenty of test subjects, and no friends that you'd have to feel bad about.

David thinks for a second. "Yeah, but **** reduces inhibitions, so doc may not consider it a fair test."
"Man, there's some hotties at those parties I'd love to use that **** on!" you say wistfully.
David chuckles. "Don't know if Doc would appreciate that either, though, you are right. We could have quite a bit of fun!"
"Well, since, according to the higher ups at the university, we're being unethical anyway!"
David smiles again. "You're thinking with your dick!"
"Hasn't let me down yet!"
