In printing, the "!" character is also known as a "screamer" (among other more offensive terms).

When little kiddies are balancing themselves atop a thick wall or jumping on and off a 6-inch step, you will often hear them screaming "MUMMY!!!! MUMMY!!!! LOOK AT ME!!!!". (or words to that effect). The mother's response (after the 1st couple of times) tends to be "Yes Jimmy" (and later no response at all, except for perhaps "GET DOWN FROM THERE!")

PR guys and some merchants have got (just a little) past the "little kiddie" stage. So their  attention-grabbing technique is to scream 1st, then say "Look at me". OK, they got slightly computer-literate, but they're still jumping up and down 6-inch steps.

:biggrin:
