If you have been following my Twitter feed in recent weeks you know that I’m kind of obsessed with three things. There’s ABC’s “Scandal,” which is this generation’s version of “Dynasty” without the camp or slap fights (yet). There’s the silly “boots and pants” ad with Maxwell, the creepy talking Geico pig. And then there’s Pharrell Williams’s infectious song “Happy.”

The tune has been around since “Despicable Me 2” hit movie theaters last July. But it wasn’t until last month that I heard a snippet of it in an ad for some audio speakers a month or so ago. And ever since, I haven’t been able to get the song out of my head. It’s not that the lyrics are anything magical. I mean what exactly does it mean to “clap along if you feel like a room without a roof?” Yet, none of that matters when you hear the beat.

When Williams performed it at the Oscars this month, I couldn’t help but pull myself off the sofa to shimmy along. The joy the song generates is simply irresistible. Just how irresistible was delightfully demonstrated by Rep. John Lewis.

Lewis is a civil rights icon. He was arrested and beaten multiple times in the early years of our nation’s long and bloody march for civil rights for African Americans. His speech at the 1963 March on Washington as a young man was as sobering and emphatic then as his speeches on justice and equality for all Americans are today as a 14-term member of congress.

Given all that Lewis has been through, to see this living legend git down to “Happy” — and on the International Day of Happiness, no less — made me smile. And I don’t know about you, but when he says, “This is my song” while doing a backyard barbeque hip wiggle, Lewis once again spoke for me.
