Some people (and I won't say who) are difficult to buy for. But I believe I've found a solution with this handy-dandy How-to Guide.

First, Identify the Nerd. Check. (And uh-oh . . . who knew that giving the answer "42" to any question asked was nerdy? But this isn't about me.)

Second, identify the obsession. Check.

Third, identify something outside the norm that references that obsession. Check.

Fourth, buy it, and doll it up so it looks even nerdier in the wrapping.

Good to go.
