Around 8 this morning, that question for the ages was a top Google search, thanks to Stewart’s performance of “Maggie May” on last night’s American Idol finale. (Plaid-itude check!)

“How old is Rod Stewart?” What’s with the complete sentence — have people never heard of Wikipedia? There’s a special place for ages in the info box.

Quick! Without clicking for the answer, how old is Rod Stewart? This is a 30 Rock-inspired challenge — try not to make like Lemon and Pete by guessing “25?” and “50?” Both are dead wrong.
