parking signs are good for the head

i thought no one was there. street parking signs--not where the stand is directly behind--with it's springy give and forgiving flat surface, is
really good for head-butting practice. i was having a ball with it until i noticed i wasn't actually alone and people were hurrying away. my wife
didn't find the whole thing funny at all. it also makes a really cool 'clang' sound.

"OMG RUN!"

Ninja rule: Always assume someone is watching and listening.
