Propofol is a short-acting, IV anesthetic. Are you thinking of depo provera?
No, I was hoping to trigger something equally ridiculous in succession, like:
"No, that's a prophylactic. Propofol is a ruler of ancient Egypt."
"You're thinking of a pharaoh. Propofol is what makes a helicopter go."
"That's a propeller. Propofol is a combat formation that involves foot soldiers forming a shoulder-to-shoulder wall."
"That was a phalanx. Propofol is a country made up of over 800 islands south of China."
"No, that's the Philippines. Propofol is an intangible quality that is given to respected individuals."
"You're thinking of prestige. Propofol is the NHL team in Pittsburgh."
"That's the Penguins. Propofol is..."
You get the idea. Hell, give me a beer and an hour and I'm pretty sure I can keep going indefinitely.
