My best impressions are of Elmo and Big Bird. Aside from those, I'm good at Cookie Monster (closer to David Rudmans), Grundgetta, Grover (a little bit), Prairie Dawn, Gonzo, Uncle Deadly, Beaker, Swedish Chef, Link Hearthrob singing, a little bit of Fozzie (closer to Eric's)and, just recently, I've learned I can do Miss Piggy. Also, would Barkley count? Even though he's just a dog. Edit...forgot to put Camilla.
