Dean remembered this part well enough and picked Sammy up, placing his head on his shoulder. He patted his back gently, making sure Sam's head was firmly on the burp blanket. Getting peed on was enough for one day; he didn't want to get spat up on as well.
"C'mon, 'ammy, burp." He chuckled at the kicking feet, and started to hum some Zeppelin. Maybe it'd sink in and he'd like better music when he got back to being Huge Sammy.
