When you're talking with someone on the phone, and suddenly it sounds a little more echo-y on their end, do you think . . . did they just go into the bathroom? Well . . . you should.In a new survey, 56% of Americans admitted to using their cell phones in the bathroom. And we say "admitted" because we STRONGLY suspect there are some people who lied.Of the people who take their phones to the can, 70% make calls, 62% text, 20% listen to music, 19% check Facebook and Twitter . . . and 7% actually pull up something on their phone to read.
