I wish that someone would come up with something like this for telephones. Perhaps a breathalyzer on the handset that would disallow people from calling my number after having had a few drinks. It would make life much easier.
Don't drink and drive
Don't drink and e-mail
Don't drink and make phone calls
Don't drink and post on internet forums
And those are only a few of the things that one shouldn't do while intoxicated. The list is virtually endless.
