A 14 second video uploaded to YouTube on Wednesday shows the unidentified man reminding himself of the phrase as he filmed his black Audi brand vehicle, covered in white, brown and yellow bird excrement from trunk to hood.

Experts suggest the best way to remove bird droppings from your car is with warm soapy water and a sponge.
