Backstory: Fozzie's started going to therapy and has become more assertive. Good stuff! He eventually goes back to his old ways and sums it up here (the line happens at 1:35 but why skip ahead? It's all good.)
The aggro Fozzie storyline serves to distract from an episode that's basically just a bunch of aroused Muppets. Raquel's appeal apparently crosses all boundries of age, species and one's status as a Fabricated American (to borrow a term from Greg the Bunny.)
Also, this episode has the Muppaphones!
