Here's a Hint for Doctor House's Video Diary 1 of 3.

The Rock Doctor House Loves So much. He has visited it every single day ever since he was born (no joke everyday @ 6 P.M. PST he shows up there on ice shelf for 10 minutes then he leaves.)
The Bincoulars That are to small for Doctor House's Eyes could have very well infected his eyes.

Doctor House's Blue Puffle that he got with bubble gum on it.

The pool is swam in by dozens, but that mysterious Pink thing in the pool maybe what caused House's Sickness.

Doctor House ate tons and tons of pizza. He loved it. Until he ate to much and some of it came back up.

The ICE CREAM! lol. So funny. Yea House uses this to cure people all the time and he himself loves it.

the adopt a puffle catalog is quite an interesting piece of evidence that may have caused House's sickness. Why is it so interesting? Because tons and TONS of penguins use it.

Anything he has been doing has to go. Yes it is true that you can develop allergies, but anything he has been doing his whole life has to go. Also, Another thing that can be eliminated is something that isn't quite so obvious. If everyone has done something, and only House got sick, theres no way that could have been the cause of his sickness. That eliminates two things. Here's some pictures of all the pieces of evidence that could have caused house's sickness.
