I'll Take the Couch - S1.E10

An unexpected visit by Hiro's parents throws the Stitt household and the entire town into disarray. The Karutas' arrival coincides with Charity's 16th birthday complicates matters further, but not as much as the house's utter destruction. Crashers from another dimension and plenty of teen angst combine to provide a night no-one will forget. Strangely, everyone has a good time except Charity whose attempts at sabotage all collapse - much like the Stitt house after their guests finally leave.
