In walks the teacher.
Student: "Hey, is there some sort of lighting device in the room?"
Teacher: "Huh?"
Student: "Is there something I can light a cigarette with?"
Teacher: "No, there's nothing like that in here. There are gases in this room."
Student: "Well, what do you use to light them?"
Teacher: "We don't! They would explode."
Student: "So, there's not a bunsen burner or something?"
HAHAHA...Are you kidding me?!
So, here's what I think: If you have to ask your physiology lab teacher for a bunsen burner so you can light a cigarette and feed your addiction, then you might want to consider quitting. I'm just sayin'.
