I don't suck on them - I have a milking machine for that!!
The milking machine is an expense, probably a depreciating one (check with tuliptree). That's good. If you had to rely solely upon sucking (with your mouth) the squirrels and ostriches, you'd end up paying more in taxes....I think....unless what you're doing is black market dairying...in which case, I should inform you that this conversation is being taped by interpol....
