Untrue. I have watched a guy do it before. I tried to do it myself - ran at him full tilt.....and basically bounced off and likely landed in his turd piles. I don't know, it was dark and I was drunk.
The guy got the cow over though.
Yea and I'm fucking a girl from Niagara Falls -- you wouldn't know her.
The urban legend of cow-tipping relies upon the presumption that cattle are slow-moving, slow-witted and weak-legged, and can easily be pushed over without much force. However, cattle do not sleep while standing; they only rest that way, and they are easily disturbed. Furthermore, numerous sources have questioned the practice's feasibility, since a cow represents over half a ton of weight that would easily resist a lesser tipping force.
A 2005 study led by Margo Lillie, a doctor of zoology at the University of British Columbia, concluded that tipping a cow would require an exertion of 2,910 newtons of force, and is therefore impossible to perform by a single person. Her calculations found that it would take at least two people to apply enough force to push over a cow if the cow does not react and reorient its footing. If the cow does react, it would take at least four people to push it over. Dr. Lillie noted that cattle are well aware of their surroundings and are very difficult to surprise, due to excellent senses of both smell and hearingbut that according to laws of static physics, "two people might be able to tip a cow" if the cow were "tipped quickly — the cow’s centre of mass would have to be pushed over its hoof before the cow could react." Dr. Lillie's study has been replicated by other researchers, who confirmed that at least two to four people can, in fact, tip a cow.[
