If you don't already know, an iPhone is so sophisticated that it is capable of emitting farting noises. Keep that in mind as a Florida firm raises a stink over Loveland-based InfoMediaInc.'s decision to use the phrase "pull my finger" in promoting "iFart Mobile," one of the many prankish 99-cent applications for the iPhone. Florida's Air-O-Matic Inc.'s "Pull My Finger" led sales in the flatulence-novelty category, but then came iFart, which made gains seemingly because of its nuts-and-bolts marketing, which is now the subject of a legal battle, according to the Fort Collins Coloradoan. Air-O-Matic's attorneys want Apple to remove iFart for trademark infringement, but Apple has refused. The lawyers also want InfoMediaInc. to cough up $50,000. Kevin Houchin, InfoMedia's lawyer retorts in paperwork that the phrase "pull my finger," "and derivations thereof, are generally known and widely understood in American society to be a joke or prank regarding flatulence," as Wired writes.
