Two zombies were discussing how they were going to go out and satisfy their appetites.

"I think we need to be a little more authoritative and menacing," Zac said. "These potential victims seem to be taking us for granted."

"I don't know about that," replied Hal. "I think a subdued, common sense approach is the better way to go. That way they're more likely to let their guard down."

"I've listened to you take the polite approach when you get the urge to munch on gray matter," countered Zac. "I don't think that gets the job done."

"How so?"

"Well, for one thing, you DON'T ask your victim, 'Can I pick your brain?'"
