If you're having a quickie and want to orgasm as quickly as possible, which sex position do you choose?

Me personally, it would be with my wife on top in cowgirl position. I'm not sure if its the view or the fact I've given up control and can't adjust my stroke or slow down to ward off an orgasm. For my wife, it would be doggie with her playing with her clit.

Which position would be your choice to orgasm the quickest?
