It's the moment we've been waiting for: The gathering of the Tammys on 'Parks and Recreation' (Thurs., Sept. 29, 8:30PM ET on NBC).

Yep, in 'Ron and Tammys,' Tammy 2 (Megan Mullally), Tammy 1 (Patricia Clarkson) and Tammy 0 (Paula Pell) will all pop up to cause havoc in Ron Swanson's life.

Things deteriorate rapidly and can only be solved via a very special drink-off! The stakes are high and the ending may surprise you.

What else should you expect? Patricia Clarkson being awesome and then some!

1. Patricia Clarkson's Tammy 1 can only be described as deliciously chilling. She's so pale, so evil and so anti-Tammy 2. Ron Swanson calls her a "psychological mastermind." Get this, she's been in Ron's life for longer than you think. Her showdown with Tammy 0 and Leslie is legendary! Somebody get this woman an Emmy, stat!


2. "Awww, Snapple!" Ben hangs with the Entertainment 720 gang and gets a pretty sweet new nickname from Jean-Ralphio. Nerd stuff really excites Ben.

3. Prepare to see Ron Swanson as you've never seen him before. Below you'll get a peek. He's in a bit of a "pickle."

4. Chris and Ann together again!? The two bond ... over diabetes.

5. Leslie Knope. Drunk. If you thought 'The Fight' was hilarious, wait until these very amazing scenes.
