Harry, I am a Potter!!!

This is part of a conversation that I overheard in one of my dreams:

"Harry, I am a potter."
"What's a potter?"
"A potter is someone who makes pots."
"Oh. I thought it was someone who carries your luggage at a hotel."
"That's a porter. I'm not a porter, I'm a potter."
"What about a reporter?"
"That's someone who works for a newspaper. A reporter is someone who reports."
"It's quite confusing, don't you think? Potter, porter, reporter..."
"Well, you just have to take the trouble to find out and remember, that's all."

Then someone lets out a slow-sounding fart.

"What was that?"
"What was what?"
"That sound."
"What sound?"
"Didn't you hear it?"
"No."
"It sounded like 'port'."
"Heh heh, sorry son, I farted."
