So last night the “American Idol” crew was whittled down to three. Ciao, Jason Castro! (Cue violins at John Norris’s house.)

Now we are left with David Cook, David Archuleta, and Syesha Mercado, and the competition is really heating up. Because it’s great to be in the final three and all — but how many of you remember the number three’s of seasons past?

(Um, we’ve posted a photo of Syesha above because — not to be too presumptuous — let’s just say that an office pool of the 29th floor would reveal that most of us are betting our paychecks a David vs. David showdown.)

Can you remember all the number three’s? It may not be as easy as you’d think. Check your answers after the jump.
