My partner was living in NZ, I was still in the states. I got a video camera and did a dance to "She Wolf" by Shakira and dropped trou right when Shakira sings "aah-oooh" in that breathy way she does. (Seriously, great song, look it up if you don't know it.) My package fills out the dog snout, so it really looks like I have a wolf in my pants. My partner found it hilarious, she loves it when I wear them now that we're reunited, and frankly, I still get a kick out of taking my pants off in front of a mirror and making dog noises.
There's no fly, though, so be warned that you're gonna have to pull em down when you have to pee. On the plus side, "gotta go face-peel the wolf" is a great euphemism for using the bathroom.
