A cunning and insane plan

"How'd you know we were leaving?" Cerebrum called back down.
"The intercom, of course. We listened in on your conversation."
"Keto, you idiot, you were supposed to hit the mute button!"
"I did," Keto protested. "I don't understand. It's a Model 950 Barrint."
"The Model 950 Barint, no wonder! The buttons were mislabeled on that model.
The crank volume to maximum was labeled as mute. What on earth were you
doing with such a cheap model?"
"Maybe I'd be able to afford a better model if someone wasn't blackmailing
me for all of my money."
"I hate it when that happens," Cerebrum agreed.
"Just shut up, will you?" Keto snarled.
"Wait, I've got it!" Cerebrum shouted, swinging back down into the room.
"Since I'm unaffected by the spores, Keto can analyse my blood, isolate the
factor and then create a vaccine."
"I thought we weren't affected because we were moral vaccums, like the civil
service?" Keto said, nastily.
"I do have morals, you know. It's just that the wide variety of drugs I take
surpress them. Primarily because I'm completely insane without them. But if
I was sane," he shuddered. "I'd be a very moral person."
"Fine, let's do it then."
A few minutes later
Keto looked up from the microscope. "I've never seen a larger concentration
of chemicals in one drop of blood. There's only one way to isolate it." He
ran off for a minute, and returned holding a bottle, he squirted the
contents over the blood sample.
After a pause, Cerebrum finally said. "Even if I was willing to accept the
idea that French's mustard was capable of isolating the specific drug that
eliminate my morals, wouldn't it be a better idea to open the casing of the
sample first?"
"It's ointment," was all that Keto would say.
"Wait, I'm getting a message on my PDA. It says we have to go to the bar on
level nine, if we don't want to be torn limb from limb by murderous crowds."
