Barack Hussein Obama

Has sure a sense of drama

Not even would Abraham

Have dreamt he'd be Uncle Sam

Limerick #13: Kronecker

There once was a gent, Kronecker.

'Sir Succinct' was his moniker.

He invented his delta,

And told Levi-Civita,

'My tensor is laconicer'

Michael Jackson

Had a black son

Who yet might

Turn out white

Clerihew #01: Feynman

Richard Phillips Feynman

Was no Simple Simon.

Asked to prove himself, he

Came up with Q.E.D.
