The conversation between the old feeble hobbling sexton and the writer is extremely funny. Contrast the behaviour of both bringing out the humour.

This was asked before but I'm really not sure where it is in the book. The asker mentioned it is in chapter 7. This is all I could find,

"I shock respectable sextons by the imperturbability I am able to assume before exciting inscriptions, and by my lack of enthusiasm for the local family history, while my ill-concealed anxiety to get outside wounds their feelings."
