This was my husband's original idea for what he'd say during our marriage vows (thankfully the day before our wedding he found something a whole lot more beautiful, but it's till cute):

Said the pelican to the elephant

"I think we should marry, I do.

'Cause there's no name that rhymes with me,

And no one else rhymes with you."

Said the elephant to the pelican,

"There's sense to what you've said,

For rhyming's as good a reason as any

For any two to wed."

And so the elephant wed the pelican,

And they dined upon lemons and limes,

And now they have a baby pelicant,

And everybody rhymes.
