I have just been re-reading bits of Titus Groan by Mervyn Peake. It is not a work noted for comedy, but I came across one sentence which made me laugh out loud:
But both the Doctor and his sister found that the Ladies Cora and Clarice had not been paying the slightest attention but had been staring at Steerpike more in the manner of a wall staring at a man than a man staring at a wall.
Definitely a “I wish I had written that” sort of sentence.
I have searched for a copyright-free picture of Peake, but I came up against what you can see in the picture above. The Wikipedia entry has a photo of him though.
