Offer to take a picture of the girl and your wife. Pick a well lit area. On the first picture, zoom in on the yoga pants, or simply get a neck down shot (use your judgment to get the most "bang" for your single-picture buck). Look at the camera and say, "****, that came out blurry as hell; let me take one more." On the second picture, take a real picture of her and your wife. Show that to them. "This one's nice."
Post thefirst picture to SPS and immediately delete it from your phone or camera.
I agree with what Shmuley said. There's no way that this girl or her "toe" will live up to the expectations of this board, but I still want to see it.
