Happy Moter's Day

I'm not sure what Moter's Day is. Is it a day to celebrate motors? Like a motorcycle or a motorboat? What are we supposed to do for it? Give them some new oil or a tune-up? Let them take the day off or use them more? What's next Robot Day? Vacuum Day? Lawnmower Day?

Oh and don't worry about giving my regards to your Mom. I gave it too her over and over and over again last night.
