I still NEED to buy a Xenomorph suit... even the wife thought it brilliant...
Go for a walk on the walking tracks around here when the joggers come out at evening. Either hide in the bushes, or actually jog along in it... be an absolute HOOT!

Even put jogging shorts and a sweat band on
Not sure how long before the police would be called, and may get pepper sprayed

I could always hiss at them back or spit acid LOL
