G'day! I mean b-day

My sister emailed me a birthday limerick. It's way too rad to not share.

I once knew an athletic man,
Who developed an ingenious plan:
Stay physically fit
And "oldness" won't hit!
But then he turned thirty, so it turned out he was wrong, because even though he was still in good shape, he was SOOOO OLD!!!!!

The literati greats have nothing on Anna. Take that, Proust!
