The Angry Beavers/Recap/E19 Trees Company

Norb wants to be left alone so he can put together his "Last Year's Model" model. Dag takes it personally, and storms out of the dam, and sets up a party in a tree with a bunch of friends. Norb eventually gets curious and tries to spy on the party, but his attempts keep getting foiled by Dag. At the end,.

Tropes:
 * Exactly What It Says On the Tin: Norb's models "This Year's Model", "Next Year's Model", and "Last Year's Model" are just models of said phrases.
 * Fridge Logic: How was Norb able to build the first two models without Dag annoying him?
 * Hollywood Healing
 * Leave Me Alone
 * Shout-Out: The title is a reference to Threes Company.
 * Sticky Situation: While Dag offers to glue Norb's model together, he accidentally squirts glue all over Norb. Dag manages to get the glue off Norb.... and a chunk of Norb's fur too.
 * Stop Helping Me!
