So our animals can't turn around for the 2.5 years that they are in the stalls producing piglets.... I don't know who asked the sow if she wanted to turn around.
There's a bit of a flaw in his logic because you can't go around just asking pigs these kinds of questions and waiting for them to answer. You must first give them a xylophone. Then, you ask a yes-or-no question like, "Would you like to turn around ever?" If they hit middle C, that's a "no;" if they whimper in agony, take that as a "yes." It's not that hard, you just have to remember to bring a xylophone.
