Okay so about Charlie’s penchant for iodine. This is another running gag through out the series, and I chose to play a little oblique with it. I want the audience to infer what it means rather than spell it out — as I am about to do here.

The inspiration comes from an anecdote Jon shared with me about Chaplin. Apparently, Charlie believed that if he painted his penis with iodine, he wouldn’t contract STDs.
