He arrives today so he saves Christmas Pattersnarfing tomorrow.
Panel 1: He enters the room and asks if anyone's home.
Panel 2: Mike yells "Uncle Phil!" and he answers with a hearty "Far out! Who's the big dude?"
Panel 3: Mike acts like the average kid he is and asks which suitcase has his present in it. Elly cuts him off in mid-sentence because that's kind of rude.
Panel 4: It doesn't matter to him, though. He'll just help Phil unpack.
Summary: Tomorrow, Phil whines that Elly is the Grinch that stole eating like a God-damned pig at Christmas.
