That hole is your goal?

^if I could get 1/2 that size!!!

That looks painful.. Make sure to lube your tiny man first.

Hell my little grub worm would fit in there, and still have room to hit the sides like ringing a dinner bell

Ding dong. Come and get.. mmeehh.

and it is called...
the sir richard knocker key chain retention device-

allows you to keep your's and 3 friends key chains safe and secure -
gone are the days of your drunk buddy wanting his keys back to drive home drunk after a night of party party party... esp. when you tell him-
well buddy- you gotta dig down there and find your set of keys- you grab the wrong one- and well- things might get interesting.

Yeah just don't touch the 'master' key.. Looks like someones fuked up idea for a hall pass too
