This episode contains footage from the un-broadcast pilot. Because of this, Vince's hair changes colour a few times. (See goofs)
During this episode Vince says it takes about 90 mink to make a small ladies glove, and Howard adds that this is because mink are not very good at sewing. It actually takes approximately 60 mink to make a full length fur coat, but it is true that they are not very good at sewing - as they lack opposable thumbs.
