Never start bragging before you cross the finish line.
I was racing online in my superduper Hugger Orange 09 Audi R8 5.whatnot quattro, at Indy, and just as I exit the final turn, with my HUGE lead, I shout triumphantly "GOOOOO WONDER PETS...YAAAAAAAAAAAAAAAY" (OK, quick story, my kid loves the show, that's why the name...etc.). I take a quick peek back to see how much I spanked them...when CRAAAASH...right into the wall at the entrance to pit road. I did not finish first, and EVERYBODY laughed at me. Trust me, wait until after you win. I didn't love it.
And yes, btw, I did paint my Audi Hugger Orange.
