It's Cheaper Than Electricity And Petrol

The following conversation happened so fast that I couldn't keep up, so apologies if it doesn't quite make sense, but I just had to share it because it's so incredibly South African.

One of my colleagues was asking us our (financial) opinion as to whether he should pay off his credit card first or first spend money erecting a fence around a new property he's bought in a rural area. He then mentioned about local livestock mowing the lawn, but if the fence is erected:

Colleague #1: "...we can't tell Marta to bring her sheep to mow the lawn..."
Me: "Are you serious?"
Colleague #1: "Yes! we found two goats in our yard on the weekend."
[Discussion about the random goats that appeared on the property and "mowed" the lawn and how that wouldn't have happened if they had the fence.]
Colleague #2: "It was so cool when the goats were roaming around there...."
Colleague #1: "Yes, and we can get 10 sheep for free to come and clean up, otherwise we are going to get the bill from the municipality every year about cleaning up our plot."
Colleague #3: "Is it sheep or goats?"
Colleague #2: "No...Marta at the post office - she has 10 sheep..."
Colleague #1: "...she's looking for a restaurant for them..."
Colleague #3: "...so, free lawnmower and manure?"
