If you're still planking, it is time to get it together and start 'Going Ostrich.' This planking-inspired activity is ten times as difficult and 50 times more extreme.
Going Ostrich means sticking your head in anything that looks like it could use a head in it. For example, a guitar, the sand at the beach, a toilet, a trash can and a lady's behind. This urban sport requires excellent balance and the ability to completely embarrass yourself in public.
The original ostrich Nathan Barnatt somehow manages to do it while rhyming each location he sticks his head in with the next one. Nathan Barnatt is a trained professional in Going Ostrich so keep in mind that only experts should attempt to rhyme at the same time.
