“In Theory” is hilarious and thoughtful both — should Data date? lols ensue! — but my favorite part is when Riker is shown as the manslut he really is. *dies* It topped my previous favorite part shown only a scene prior of Worf warning Data about hurting the lieutenant under his command if he chose to persue (or not persue? o.O) a romantic relationship.
But srsly, manslut Riker is the best.
