Christmas fever!

Here we sat on Monday, ready to go bowling at Daddy's company Christmas party, when the Grinch came in and stole our fun.

He arrived just after Quinn's nap in the form of a 103.8-degree fever, causing one miserable and slightly nauseous little boy.

But this truly is a tale of Seuss-ian proportions.

That 'ol Grinch was vanquished not long after Quinn hit the sack. He woke the next morning a brand new boy, ready not only for school but his first-ever Christmas concert.

It was a virtuoso performance by the Happy Hearts preschool of Aloha, Ore., with Quinn singing loud, ringing his bell, and stroking his faux Santa beard on command in front of a standing-room-only crowd.

Their reward was a visit from the big man himself, all the way from the North Pole -- a cameo appearance we've captured here for you on videotape.

Enjoy it, along with the marvelous singing.

Even the Grinch cracked a smile.
