All tied up: As a public service to all the Mirror readers anxiously awaiting their upcoming graduation and prom night, heed this advice: learn to tie your tie. A clip-on is a surefire way to not get laid, and accidents happen on the dancefloor so you can’t rely on the knot someone did for you earlier. Besides, it’s a necessary life tool and now is as good a time as any to learn. Caspar Isemer’s Web site covers everything from Windsors to bowties, and even provides fashion advice for job interviews. Look your best at: www.tie-a-tie.net/.

Fun with film: A recent Internet phenomenon has editing whizzes mashing up classic movies with funny themes to produce a mock movie trailer. For example, someone turned the original Ten Commandments into a cliché-ridden high school comedy. Or imagine The Shining as a heartwarming family film, complete with “Solsbury Hill” in the soundtrack. These and the equally hilarious Must Love Jaws can be found at www.milkandcookies.com/keywords/moviemashup/.
