2. A witty e-mail signature. Quotes and song lyrics should be heard during toasts and karaoke performances, respectively. Don't let your electronic correspondence become the digital version of a motivational poster.
3. An empty refrigerator. Your larder should be amply stocked, your pantry provisioned. Always aim to be ready to create an on-the-fly, three-course dinner for her...along with breakfast in bed.
4. PlayStation thumb. When they're relaxing, grown men can behave like children. But if you devolve long enough to cause calluses or button-shaped bruises, you're assuredly missing out on life.
5. A key chain with a bottle opener. This bauble is both a gauche reminder of your college days and proof that you don't know how to apply leverage using available, impromptu bottle openers: a lighter, the back end of a fork.

14. Code words for ugly women. Actually, code words for anything.
15. A Nerf hoop in his living room. Keep the adolescent accoutrements where they belong: in the rec room or above the wastebasket in someone else's office.
16. A secret handshake.
17. Drinking glasses with logos. Especially those kitschy McDonald's Hamburglar ones.18. A recent story with the phrase "So I said to the cop…"
