Twitter user Clayton Hove may have just written a little comment to generate a few likes or cause some laughter by tweeting 'Saw a bird had crapped on a Smart Car. Totaled it.' Hilarious to think bird crap had damaged a Smart Car, making it a total write off. So, how much bird crap can total a Smart car? The answer is 4,500,000 pigeon craps, or 360,000 pigeon craps, or 45,000 emu craps.
