We just sat down at the table to eat our Thanksgiving dinner.
We got an unexpected problem.

The turkey has to take a ****.....
We dont want to put it on the toilet since we are going to eat it, so
I am trying to connect some plumbing from the turkey to the toilet.
But, there's a problem. I got copper tubing, galvanized pipe, black
pipe (which I know would be best if the turkey passes gas), and PVC
pipe. Also got some good radiator hoses.

I dont know which pipe to use.
Can anyone help?
