People dial wrong numbers all the time. What can really get you in trouble is printing the wrong phone number, especially on a product or advertisement or in a catalog. That mistake is compounded by the fact that so many toll-free long distance numbers are phone sex lines. The most recent case is Chad Ochocinco’s cereal boxes.

1.  Ochocinco meant well by printing a request for donations to a charity called Feed the Children on his new cereal, but people calling to hand over some money actually may have been “donating” to an organization of the not-so-charitable kind: a phone sex line.  For the record, the number on the box was 1-800-HELP-FTC when it should have been 1-888.  Whoops!  Funnily enough, the day the cereal came out, Ochocinco Tweeted, “order my cereal OCHOCINCOS.  Start your day with a lil suga!” Insert immature giggles here.
