I'm unusually sensitive to noticing fragments of melodies from songs. The self-checkout at Sainsbury's plays Walking on the Moon by The Police when it prints a receipt - it does for me anyway.
I enjoy anything by Armando Iannucci (except an opera he wrote, which wasn't very good). I read mostly non-fiction books, but in fiction I enjoy reading Will Self. I like slapstick silliness: Naked Gun films, Bottom, Father Ted etc. The Thick of It really makes me laugh.
