What's your pick for the grossest moment of the show?

I was rewatching yet again and realized that there are so many to choose from and it would be fun to see which people pick and why, especially because all of mine happen to be Marcus-related:

Marcus saying that he uses his ungloved nails to clean off stubborn toilet clingers Marcus cleaning his massive leg wound in a public jacuzzi Marcus using "found milk" for boob cheese

Your turn!
