How do I say "Prove it!" in Russian? I say it to my friend all the time in English, usually to be a smart a$$, as I say it after he says something that he can't actually prove. I used a translator to come up with "докажите это!" However, I would appreciate any input anyone has to give because translators are often very literal and miss the gist or general sentiment of what I really want to say. Thank you so much.
