My dog has no nose

Boss

Come in to my office.  Does it smell funny?

PTR

Why?

Boss

My last patient had urinary incontinence and I'm wondering if I've aired the room enough.

PTR

I've got a cold so I can't really tell.

Boss

How convenient.  You should cultivate that cold.

PTR

I have a 2 year old at home so there's no need. We have colds on tap.

Boss

How lucky you are.
