Coming in second

So this guy goes to his girlfriend's house (It's actually his 'friends with benefits' partner's house), pulls out a handful of condoms, and says, "Which color would you like tonight, baby?"

"Silver," she says without hesitation.

"How come silver?" he asks. "I'd of thought you'd wanted gold."

"I would have," she says. "But for tonight I'd like you to come in second."
