It was dark in the sewers under Manhattan, where the five of you were trudging through the horrible stink and occasional sewage. You were trailing behind The Doctor, and ahead of Frank and Martha, who were chatting, and Solomon. "Ah bloody hell," The man ahead of you murmured, running a hand through his beloved hair. "damn humidity will ruin my hair."

Can this man walk 10 yards without making a comment about his hair? You've only been with him for a couple of hours, and it's driving you mad! You were about to say something snarky, before you felt something SQUELCH! underneath your foot.

Lifting up your boot, you had stepped on... HOLY SHIT IS THAT A BODY PART?!

"Whoah!" The Doctor shouted, shining the light on the gelatinous object, now with the imprint of a shoe.
