Once Upon a Time...
...in a gun shop long ago and far away, there was a bunch of that Indian surplus .303 for sale. Tamara and A Gunsmith Who Shall Remain Nameless were standing behind the counter when a man came in and began looking over the merchandise.
The man saw the Indian ammunition and shook his head and said "You know, this stuff ain't even got gunpowder in it. It's all full of this stuff that looks like spaghetti. I took some apart with a genetic bullet puller." And then he left.
"He needed a genetic bullet puller," said Gunsmith Name Redacted To Protect The Innocent.
"Too late," said Tamara, "There was a kid in the car."
I wound up explaining the jokes and it was, of course, a whole lot less funny that way. (On linking back, I now notice that Tam provides explanatory links, inline.)
Okay, I'm a geek. And I admit, I'm torn between wistfulness that fewer and fewer people get the references, and a purely prurient wish that I could have been there to see that. :-)
