Screwing up the digits of a phone number can have interesting results, especially when it's a helpline, that gets routed to a phone sex line.
Something similar happened to my workplace awhile back. We had a 1-800 number for our helpline, and a 1-888 number so people could call the office toll-free. The president of the board was trying to get the office but instead of dialing 1-888-[office number], she dialed 1-888-[helpline number]. The results were, shall we say, colorful.
