Where Have All The Good Practical Jokes Gone?

Remember when you could pull pranks on your pals and not get sued or arrested? Remember life before caller ID? You could call a bowling alley and ask the clerk if he had 12 pound balls, and when he said yes, you said "then how do you walk?" and hung up. Those were the days. I was reminiscing the other day and decided to look up classic practical jokes. I have listed some of my favorites and put up a poll to vote for your favorite. You can't do any of these now without Homeland Security arresting you and shipping you off to Gitmo, but they were a riot back in the day!

• Icy Hot in the jockstrap - This one happened to my bother Turk. He was a real douche to one of the smaller guys on his 9th grade football team, always giving the kid a hard time (we'll call him "Leonard"). Finally after getting the business one too many times from Turk, Leonard put a healthy dose of Icy Hot in Turk's jockstrap. The resulting screaming fit and eventual shoving of a water hose down his pants led to Turk changing schools from embarrassment.
• 12 pound balls - The aforementioned gag where you call the bowling alley. If a chick answers the phone...ABORT!
• Vaseline everywhere - This classic is cheap, easy and elicits a satisfying look of revulsion from the butt of the joke. Put Vaseline on doorknobs, phone receivers, car door handles, light switches, hairbrush handles, you name it. The look on the victim's face is priceless.
• Running refrigerator - Call the meanest old bat on your block, preferably one who is paranoid and has early-onset Alzheimer's, and ask her if her refrigerator is running. When she says yes, you say "you better go catch it!" and hang up. Do it every 4 days or so from a different pay phone each time. Eventually she'll have a stroke.
• Sign of the times - In some smaller towns, businesses, especially restaurants, advertise specials on signs with removable letters. This is a great time to change the specials from Seven Layer Lasagna $4.99 and Hot Meatball Sandwich $3.99 to Semen Sandwich $3.99 and Seven Ball Lasagna - $4.99. Make sure the cops don't see you...under cover of darkness is the best.
• Ganked Kool-Aid - This one is a great one to play on kids. Pour out their Kool-Aid. Put in water, 3 tablespoons of salt and red food coloring. Shake, serve and skedaddle. It's friggin' awesome!
• Free legal advice - Go down to your local county courthouse. Post a notice that says free legal advice, no charge unless you win your case. Then post you friend's phone number. Sweet!
