In the board game 'Dream Phone' you would use the included pink phone to call cheesy looking American guys with a number starting '555-'. Someone may have given you a tip, something like "this guy doesn't eat pizza". So then you would have to eliminate all of the guys that didn't like pizza.
Some were blonde haired studs and some were skinny geeks. You used to ask them to go on a date with you, or find out who fancied you.
