Cattle Battle

Jeff went to the junkyard yesterday because now that I've forbidden more cars at the house I'm pretty sure he's trying to sneak them in piece by piece and he sent me this awesome picture:

Obviously a picture such as this raises several questions, so we had the following exchange when I got home from work:

LAB:   Are all cattle girls?
Jeff:  Oh my God.  No.  Cows are female.  Male cattle are steer.
LAB:  Oh.
Jeff:  If they were all girls, how would you get more?
LAB:   I don' know.  Animal husbandry isn't my specialty.
Jeff: The fact that the words "animal husbandry" exist in your vocabulary terrifies me.
LAB:   I went to college in Alabama.
Jeff:  Clearly.
LAB:  But all bulls are male, right?
Jeff:  Yes.
LAB:  Then how do you get more bulls?
Jeff:  I'm really glad we had this talk.
