Somehow I am thoroughly amused by this Public Service Announcement that has been in circulation in order to encourage parents to play with their kids outside for at least 30 minutes a day (aka getting out and doing something active). While the thought of a dog playing with a slab of butt kind of grosses me out, it definitely gets the point across. Check it out for yourself.
On that note, go outside and play with your kids already. No kids? Well that doesn't leave you off the hook - just go outside and do something active for 30 minutes.
