I went in search of information on the phrase "till the cows come home". First I didn't put a whole lot of effort in to my search. Second I didn't find much information. Pretty much as many may know, it means a long time. As for the origin, there didn't seem to be much information on that that I found. I suppose you could say you'll be waiting till the cows come home to learn any more about the phrase from me. You won't have to wait to see a picture of cows though.
Moove over because I have one here for you. I drove down a back road after I dropped Gibbs off at the groomer Monday. When I saw these cows I stopped to say hello
Me being me, I played with it. Not a huge difference but it looks more like a painting now than a photo.
What is it that you'll be waiting for till the cows come home?
