Thin One
From Tardis Wiki, the free Doctor Who reference
The Thin One, along with his partner, the Fat One, were part of the Anglican Regiment of the Church stationed at Demons Run. The two seemed to have no names, instead using "the Thin One" and "the Fat One" to refer to each other. When Lorna Bucket asked them if they had names, they said that they were the "Thin/Fat Gay-Married Anglican Marines" and asked why would they need names.
