In the episode "One of a Kind" (when Skulker hunts danny for the first time), near the end when Lancer reads the article about Danny finding out that the gorilla "Samson" is a "Delilah". He puts Danny's paper on the desk. Look at Danny, you have to have a quick eye for this-his eyelids turn yellow!

I know it's a coloring mistake, but it looks really funny.
