well of course they are.

at least the pigs still in the poke - no one really knows what it will be like. there is the distinct possibility that it will be a nice pig.

the alternative is that you put up with the likes of Musket, this man clearly knows everything, he's a professor,

who are you going with - Sherlock the pig in the sack, or Professor Moriarty.
personally I'd go with the pig every time ....better manners!
