I went into a local video store recently, one with a royally-themed name on a street of higher education.

On a whim, I decided I wanted to see a particular Rambo movie. I approach the counter, where a clerk, about 22-23 years old, sat doing whatever.

"Do you have Rambo IV?" I asked.

The anger welled up from a place deep within his film geek soul, but still, he's a retail professional, and he tried to hold it back.

Which is why he hissed, and not screamed, "There is no Rambo IV."

"Whoops," I said. "I meant the one where he goes to Afghanistan."

The other film-geek clerk, who I would estimate is more like 19 or 20, stiffens and snaps, "That's Rambo III" -- with an unspoken "you fucking idiot" tacked on the end.

Both of them are staring balefully at me.

This triggered a brief outburst of sniggering on my part. I apologized for any upset I might have caused by getting my Rambo movies mixed up, and then I escorted myself from the premises.
