They shall pass muster, so pass the mustard!?

Advertised on blogs:
“These pass muster!”
about some hot dogs
“Pass the mustard!”

Maybe hot dogs look good
given a cursory glance
from where we had first stood
but if looked again, askance:

How & with what are hot dogs made
but poor mistreated animal parts?
The question we evade, dismayed:
How did they end up so cold, our hearts?

But don’t ask, just chomp, don’t tell!
If tastes good, ain’t then all well?
