Okay, now that we've weeded out the naysayers (What is this, Horseville?) we're onto number 12!!!
I chose BOMB THREAT, a gift that Liz Lemon gave Jack last year for Christmas on "30 Rock." You see, his possible girlfriend (Julianne Moore with "Good Will Hunting" accent) was about to leave the city until someone (Liz) called in a bomb threat to Grand Central Station. This prevented her train from leaving the station and enabled Jack to spend some extra time with his "gal." Jack's gift to Liz was also noteworthy: the playbill from her high school version of The Genber-blind Crucible (she was John Proctor) framed in wood from the high school stage itself!
That's what friends are for people!!
