Duane's Pun(s)

If 2/3rds of a pun in P-U, do 3 puns make it smell good again?

1. Before my surgery, my anesthetist offered to knock me out with gas or a boat paddle. It was an ether/oar situation.
   

2. I tried to walk like an Egyptian, and now I need to see a Cairo-practor.
   

3. After a long hike to the top of a mountain, my wife asked me, “So what do you think of the view?” I said, “Whoopi Goldberg is OK, but I don’t like the other women on the show.”
