This approach to bringing smiles and liveliness to people reminds me of Innocent Smith, the main character in G.K. Chesterton's amazing novel Manalive.

Mr. Smith meets, proposes to and marries a young lady, then is accused of polygamy when it turns out he's already married, a charge he does not deny. The twist? He's already married to the aforementioned young lady, and this charade is something he does just for fun.

Wonderful book - check it out!
