Here in the IT *industry we, on occasion, do a little deed called "pinging". To 'ping' a computer one types in the command 'ping' and then the IP address. This sends a "hello" which, when answered, establishes that a direct line on communication is open (that's "The Roy Clark Big Note Songbook" explaination).

We inquire "Have you pinged the address?" when referring to using that command.

Nobody says "pung".

Yet:

*Have you rung the bell?
*Have you sung this song before?

Why?

... and why not "I've brung you all here to think outside the box"?
