Drunk In Charge (of a) Keyboard?

When you get woken up by an SMS at random o'clock & it's clearly from a drunk person. Rather than try to decipher it, simply reply: DICK? If they are, they'll know you aren't.

This used to require a computer keyboard, although those nifty little smart phone things are inspiring a revival (also known to affect to e-mail etc., especially during the early hours of Saturday & Sunday mornings)
