The smugglers decided to hoof it.
A co-worker of mine is an Iraq War veteran. He told me that he was once assigned to a roadblock, searching cars for bombs.
Initially, the sentries were taught the Arabic phrase meaning, “Open up the trunk.”
This was soon amended to “Open up the trunk, and take out the sheep.” Because that is apparently the standard method of transporting livestock in the Middle East.
Best last line ever.
"Four cows, recently escaped from a slaughterhouse in Malaysia today, were stopped at the Thai border. Border guards shot out both the windows and the tires before the vehicle would stop.
All four were arrested without further incident or comment. Later, a spokesperson for the cows, claiming to be their lawyer, issued the following statement:
“My clients were on their way to a Hindu temple to claim Sanctuary. This is clearly a case of religious oppression.”
Malaysian officials had no comment beyond stating that the investigation was ‘ongoing’. Under Malaysian law, suspected smugglers can be held and grilled for up to 24 hours."
“Look, if they try to stop us, just look out the back window and slowly bob your heads…”
No good; they’ll be tougher than shoe leather if not completely cremated. Try grilling for 30-45 mins…or smoking for 12 hrs. Bon appetit! 
Just by the post title I thought “Four, two in front and two in back”.
Having seen the photo, the caption that came to mind was “I said IROC, not Auroch!”
There’s always that one sad last moo and then BOEUF! they’re gone… 
I said cow tipping not tripping!
First Daisy Cowit, now this. Bad month for cows.
