Prank played on me, funny

I picked up the phone, said hello and listened to the caller.

"Do you have a mint ziffleaneous trombonulinium thrummel inducer for sale?"

WTF? This guy on drugs? So I asked him to repeat the question.
Still not believing my ears I asked d00d to spell it out for me.

I thought, OK, I'll bite and see where this goes. So I said, "ya, I got one for sale, why?"

d00d says, "Well what exactly is it?" Like I know...

I answer. "If you don't know you probably don't need it."

dood says "OK, thanks."

I say, "where in the world did you hear about this?"

dood says, "It's on the community bulletin board at the xyz grocery store."

Guess I'd better get to the store and take the ad down before any more wackos call. More on this if I can glean anything from the ad, like who put it there.....

ha ha ha ha.
Could they have just be prank calling and pretending they read an ad?

When I get these, it's always drunks, stoned losers or kids afflicted with either (or both) of the former.

I'll know for sure when I check the bulletin board at the store later tonight. The caller sounded sincere though.

Take a camera with you, get us a photo if you can (rub out your number). I'd love to see this

Also, any guesses over what a "mint ziffleaneous trombonulinium thrummel inducer" is?

I haven't the slighest idea. But the letters ziffle are a clue to me. A long time ago it was a derogatory term used among my friends. So someone in my past may be behind this.
