As fast as lightning, or possibly faster, a bolt of red zoomed on the ground of the desert. This was the Flash, on his way to another city, but taking a shortcut through a desert. "Good thing I'm so fast, or the heat would be killing me. Too bad sex is always so quick...and getting people pregnant..."
Iron Man flew down from the sky and hid behind a cactus, and when Flash ran by, he stuck out his foot and tripped him. The Flash went flying across the desert floor to who-knows-where.
"I am Iron Man, and slow and steady wins the race."
