A Rainbow Dash/Pinkie Pie slice-of-life fic inspired by this particular piece of fanart: http://imgur.com/8P7Vi (proper source needed)

After one of her signature crashes causes some actual property damage, Rainbow Dash is forced to take on a part time job at Ponyville's local Domino's Pizza. As if that weren't humiliating enough, she also has the added displeasure of being stuck with the late shift on a Friday night, and the only other pony around to keep her company is the always (and somewhat inappropriately) jovial Pinkie Pie.
