International creep like a ninja day

Some people out there with far too much time on their hands. I think it is meant as an alternative to international dress like a pirate day.

going to be held on 5th December

sounds like jolly good fun though.
...However, international dress like a pirate day is the stuff of legends!
This has been hugely popular for years its just that nobody saw them!

Had to advertise for H&S reasons due to onlooker coughing last year when one of the ninjas dissapeared in a puff of smoke.............
