"There Was an Old Person Whose Habits" by Edward Lear
There was an old person whose habits
Induced him to feed upon rabbits
When he'd eaten eighteen
He turned perfectly green
Upon which he relinquished those habits
"A Young Lady Named Bright" by Edward Lear
There was a young lady named Bright
Who traveled much faster than light
She started one day
In the relative way
And returned on the previous night
