A clerihew (/ˈklɛrɪhjuː/) is a whimsical, four-line biographical poem invented by Edmund Clerihew Bentley. The first line is the name of the poem's subject, usually a famous person put in an absurd light, or revealing something unknown or spurious about them.
“I quite realised” said Columbus,
“That the Earth was not a rhombus
But I am a little annoyed
To find it an oblate spheroid”
