::Sure, the paraphrasing is fine. I was just asking if you thought it was wrong of me to suggest that people are pushing cows over because the cows are "asleep standing up"; it's a non sequitur to say that "people think it's easy to tip a cow over because cows are slow and dim-witted and weak-legged, but actually cows only sleep lightly when standing up". 
 ::It looks like at least one other source defines cow-tipping as pushing over a "sleeping cow", so I'll add back my edit with a source.
