Man pulls evil/genius engagement ring prank on girlfriend

Redditor 'griffunk' is a brave man for pulling this trick.
He posted the following pic to Reddit with the caption "I set a trap for my girlfriend in my sock drawer on laundry day, she fell for it":

Risky move but it seems like his girlfriend enjoyed the joke. He responded to all those concerned for his wellbeing, saying:
"I am not on the couch, we are in our warm bed together, she is not a fragile pane of glass like some of you ladies commenting, we like comedy, my penis is unharmed, I have to do my own laundry next week."
Fair enough, we guess, but you should really be washing your own socks anyway.
