Top 'o' the world, Ma!

These pictures aren't new - they were taken earlier in the year in Mexico. I just saw them during the Great Photo Loss and Recovery Expedition from my hard drive and back, and they're appropriate because Rooki Kahooki's confidence and love of running around like a lunatic increase every day. The picture in the About Roo tab has been swapped for this one. 

Anybody know what "Top 'o' the world, Ma" is from?
