In the old days, kids TV commercials would tell the kids to hold up the phone to the TV, and then play DTMF tones to dial a 1-900 number. For example: http://articles.latimes.com/1991-04-21/news/mn-860_1_horror-...

Today, they can probably do the same via "Siri" or "OK Google" ... ?

Or the more modern version of Xbox live trolling when people name themselves Xboxoff or xboxinternet and wait for some one to yell their name.

The Siri thing isn't new tho you used to be able to shout at Siri trough some ones phone when you were on speaker but I think Apple implemented some voice recognition restrictions.
