Sick Cow Noise

[PedroTheChicken]

Ok so this isn't necessarily me asking for help but I remember the sick cows making this horrible noise (like a deep bellowing, it was awful but it always made me laugh for some reason) and I've tried finding a video of it without any luck so if anyone here could take one or knows of one please let me know, I just wanted to show my friend.
Also if this isn't the correct place for this please tell me and I'll gladly move it, I would hate to break any rules.
