A guy walks into a pharmacy with a suppository prescription for his wife and approaches the front counter. He hands the prescription to the pharmacist and after confirming the prescription, the pharmacist asks him, "Okay sir, what kind of pills would you like?" The guy looks around and over the shoulder of the pharmacist, and spots something he wants. He points at the wall and says, "I'll take that kind right there!" The pharmacist looks at what he is pointing at and says, "Sorry sir, but you can’t have that. It's our fire extinguisher!"
