I used to live somewhere where the phone numbers tended to start with 340 or 347. Well, 347 happens to make dip. One time when my brother was a kid, he called 347-7448 (cel phones didn't exist and area codes were only for long distance) and asked, "Did you know your number spells 'dipshit?'" As a kid I thought we were doing something horrible and bad and could get in trouble for it. Now as an adult, I bet the adult on the other end was laughing his ass off.
