Time to celebrate - it's only Friends' 20th anniversary, isn't it? And what better way to celebrate than with a Friends-themed party. Just think - you could have 'Smelly Cat' on the stereo, a good old game of Cups, and even some dancing. And, of course, to really mark the occasion in style, you'd have to pull out Monica and Ross's amazing Routine.

Friends Week: 20 years of the hit sitcom that became a phenomenon

The dance - which, we'll have you know, won them "honourable mention in the brother/sister dance category" at middle school - was brought to life magnificently during the sibling's exciting visit to the recording of Dick Clark's New Year's Rocking Eve. But if you want to recreate it, you're in luck - below, thanks to Comedy Central, is a ten-step guide to wowing your party guests...

Step 1: The Finger Click



Remember to look surprisingly threatening.

Step 2: The Slap



You might want to discuss this with your dance partner beforehand (though, of course, it's not a real slap unless you want it to be).

Step 3: The Wiggle and Leg Rub



It's all in the hips.

Step 4: The Chicken Arms



This comes after an optional leapfrog.

Step 5: The Grasp and Slide



For extra impact, throw in a pre-wave.

Step 6: The Pot Stir



Wiggle wiggle wiggle.

Step 7: The Backwards Arm Shuffle



Make sure not to bump into your partner on the way.

Step 8: The Foot Tap



You only need one. Don't overdo it.

Step 9: The Hop, Skip and Jump



If you're going to fall over at any point, it's here. Proceed with caution.

Step 10: The Leap and Catch



Feel free to switch genders if your partner is a bit, well, overweight. But don't offer to be the catcher unless you're confident - otherwise all hell will break loose.

And that's it! To see how the pros do it, watch Monica and Ross busting some moves below:
