Happy Endings - Season 2 Episode 15 -

Max is sadly retreated in his unapproachable 'bear mode', using Dave's place as a cave where even the mates aren't allowed. So the rents of the gang eagerly awaits his annual wake-up call: Brad and Jane's theatrical spring fight, make-up and expensive celebratory dinner. However it's late, and every effort to trigger it seems to fail as if affected by a butterfly effect, but in fact they agreed only to fake fights and make up quietly.
