My friend Irene pointed me in the direction of this unintentional PSA. The story is that a girl is filming some cute boys skateboarding and turns around to witness this scene. It might be fake, but it still gets the point across. Go granny!
Enjoy and share (especially with anyone with an overdeveloped sense of entitlement):
UPDATE, August 29: So it DOES turn out to be fake. According to commenter Gene W, “It’s an old IKEA commercial. Airbags don’t really work that way (you have to be moving).”
Still gets the point across: don’t honk at old people.
