Blocked for the bullseye

Okay, okay - so at 27,433 kilometres, I was a little late for the 15,000 km service on my vehicle.
But is that any excuse for the mechanic to leave the evidence sitting in the driver's seat?
For those that don't know, you're looking at the air filter for a car engine that should've been replaced a long, long time ago. Given that the engine works on an explosive mix of fuel and air, it's kind of a big deal, and probably explains why my car has been fairly sluggish over the past month.
Look closely and you'll see that in addition to the dust and dirt, it's completely clogged with grass, dragonflys, and yes, a whole bunch of bird feathers. Bullseye - I thought I'd missed 'em!
