Wow. Where to start? Loved them all. Lots of favorite lines but this got the biggest laugh:
You don't have one of those Save My Pet stickers on your door, so the firemen wouldn't have known to get him." He rubbed a hand over his face. "I'll pick one up for you tomorrow."

"Don't forget to get a Save My Idiotic Friend sticker while you're at it," House snapped.

"It'll be next on my list after I get the Ungrateful Bastard bumper sticker for you."

Also loved the way you linked each story to the next one, subtly.
