Thread killer!
Hmmm...need a pun. I extinguished that thread? That thread burned out? I'm holding the thread at the line? The wind changed?
err, nevermind. I'll stop while I'm still ahead.
I couldn't let your earlier post about killing a thread pass by without comment, I'm the one who needs a pun, HEE! HEE!
I've killed threads a time or two. Hmmm!
Will I be charged with "murder"?
