The slippery Musketeers 

A variation of the classic "slippery wizard" but this one requires 3 friends preferably people you know but if not a random can be substituted for a friend.

friend number 1 attracts female (this is usually best looking one out of group best chance of success dont worry everyone gets a turn) When back at hideout friend number 1 starts to stick the female with his pork "sword" and with a wip of his whip the woman is distracted as your friend takes over after swinging in and uses his sword once he has done same the last musketeer joins in , upon finishing the woman turns round to find out nothing because remeber you have a mask on!

Then you all make haste on the 86bus back home !

The slippery Musketeers :P
