The kind of joke you tell your dentist

Last night at my community band rehearsal, a fellow trumpeter told me a joke.

fellow trumpeter: What's the difference between a tavern and an elephant breaking wind?
me: I don't know, what?
fellow trumpeter: One's a bar room, one's a bahROOM!
me (without hesitation): Ha! Now that's the kind of joke you tell your dentist.

Wait, wait. Let me explain.

The dentist I had when I was a kid was a joke junky. Every time I went in for a cleaning or filling or braces tune up (because yes, I was that gangly tall girl with glasses and braces at one point), I had to have a joke to tell him. I at least had to be prepared to make one up, because he never failed to ask me, "ya got any new jokes?" As a result, I had a stock pile of jokes ready for him. And, because he was my dentist and not my fellow gangly, awkward school girl, they were all clean...just like the tavern and elephant fart joke.

So...ya got any jokes? Pretend I'm your dentist.
