When a person's eyesight, or perception of what they see, is so totally distorted (like the captcha codes you must enter on certain websites), they have "captcha vision."
A: Dude, what a dog you were making out with last night!
B: Oh was she? I had way too much to drink.
A: No. I mean it was a dog. It think it was a spaniel.
B: Shit! My worst case of captcha vision ever!
The scrotum forms an admirable covering for the protection of the testes. These bodies, lying suspended and loose in the cavity of the scrotum … are capable of great mobility, and can therefore easily slip about within the scrotum, and thus avoid injuries from blows or squeezes.
