I'm not really obsessed with DT's tongue. Really.

I seem to have this general impression that Ten ran around licking things and/or with his tongue hanging out ALL THE TIME. Especially in S2. But apparently this isn't the case? There doesn't seem to be much actual tongue use. Is there anything else you can think of?

• Licking the wall in Tooth & Claw.
  
  
• Licking a...thing in The Idiot's Lantern.
  
  
• Marmalade licking in Fear Her.
  
  
• Almost licking a baby Dalek in Evolution of the Daleks.
  
  
• Tongue of Concentration in The Sound of Drums.
  
  
• Licking sand in Planet of the Dead.
  
  
• ETA: Blood licking in The Christmas Invasion.

Not sure you could really count all the snoggings by various people. I suppose you could. But wasn't there more tongue in S2-S4? Just hanging out even?
