Twice, once when I was about 18 sitting on the deck drinking a beer and got it square in the middle of my naked chest from a robin. Walked over to the hose and washed off, then continued enjoying the sun and my brew.
Second time was about a year ago when I was getting into my truck at work. A seagull that had been sitting on the street lamp pole above me, took off and covered me with shit. I used the towell I keep in behind the seats to wipe the worst of it off and then went home for a shower.
Seahawks have deadly aim, and can drop what seems like a pint of shit.
