The unfaithful wife and talking sacks

So, there was this one couple, a farmer and his wife, who lived together for too long and their sex life was boring, to say the least. One day the husband went away to a horse show in a difrerent state and the wife decided to try something new. She went on craigslist and posted an ad looking for some company. Within minutes, she had hundreds of replies, a lot of them including pictures of some really good-looking guys. The wife could not decide, so she invited not one, not two, but three guys over to her house! She ran to thr grocery store and bought some liquor, deciding that they should get wasted first and have a little party and then see where things might lead. Pretty soon the guys showed up, and in real life they looked even better. They all were chilling on the porch, sipping their booze and having a really fine time-things just started getting more interesting- when the wife all of a sudden spotted her husband's bright red truck in the distance.
-Oh no! My husband is back already! Quick, guys! Hide somewhere!
However, there weren't many good hiding spots in or around the house. Then suddenly one of the men spotted some burlap sacks lying in the backyard next to the barn. Each guy climbed into a sack and curled up in a fetal position, afraid to move. Soon they heard a man's voice:
-Hey honey, I am back! The horse fair ended early!
Then the husband walked out to the backyard and noticed the sacks.
-Heey, what's that?
-Oh, that? While you were gone, I got bored and went to a local farm fair myself. These are the prizes I won!
-Reeally? Lemme see what's in there.
The husband approaches the first sack and gives it a nice kick with his cowboy boot.
-Oink! Oink! - the first guy yelps
-Must be a piglet, niiice- says the farmer and kicks the second bag
-Baa! - screams the second guy
- A sheep? Really good! - says the farmer.- Now let's see what's in here- and he gives the third sack a solid kick. Silence. -Hmm, weird- says the farmer and gives the sack a harder kick. Silence again. - What the hell,- says the farmer and kicks the bag as it it was a freaking soccer ball. Then, suddenly the sack yells:
- Don't you fucking get it, dimwit?! If you kicked and there's no sound, it must be potatoes!
