齿龈炎

齿 = 止 + 凵 + 人 : Charlie Chaplin (ch) has an aching tooth (齿), and Neanderthal Man (人) is about to help him take it out using an electrical barrier (止) in the space station (Ø3). They attached the barrier to the tooth and as Neanderthal Man will plug it into the receptacle (凵), the barrier will pull out the tooth.

炎 = 火 : Mnemonic symbol: As I just learned "itis" is the feeling you get after eating too much.

Maud Younger (y) ate too much in the anthill's kitchen (an2). She's having the itis (炎) so hard that she doesn't even wake up from the fire (火) which is spreading fast.
