milk by phone?

So today, I am house - siting for some friends of mine, and the phone rings. Of course, someone is trying to sell me something. Of course, they start rambling on about their product before I can tell them that I am not interested, ( because I knew my friends weren't interested), but all of the sudden, I actually pay attention to some of the things that the lady is saying, and I realize that she is trying to sell me MILK... OVER THE PHONE.

Only in America.

So she is going on about how this is the best milk in the world, and I say " Why is yours better than mine now?" she says " Ours comes from better cows"

I am really laughing now, so just to make her confused, I say

" How dare you insult my cow!" and I hung up.

I know, I am a jerk.
