You're getting too old for this: 25 years ago, on March 6, 1987, "Lethal Weapon" was released. The buddy-cop thriller not only cemented Mel Gibson's status as a household name after playing good-natured loose-canon (as opposed to now) Martin Riggs, but also created a social phenomenon still relevant to this day: "I'm getting too old for this s---."

The catchphrase, said numerous times throughout the "Lethal Weapon" series by Roger Murtaugh (Danny Glover), has appeared in many movies over the last 25 years, often times in reference to the put-upon police detective himself. (The recent trailer for "Men In Black 3" features Will Smith uttering a PG variation on Murtaugh's famous one-liner.)

What you might not know? That "Lethal Weapon" wasn't the first film to utilize some form of the defeated turn-of-phrase. From "North by Northwest" and "The Sting" to Murtaugh himself, enjoy a mash-up of movie characters getting too old for this.
