<human>: So I'm a college student. To some us tiny amounts of money, (ie $5-10) are a big deal. After the boring backstory designed to make me look cool the crux of my story is this: An acquaintance of mine claimed to have a handle (1/2 gallon or 1.75 liters) of very cheap vodka ($10) in his freezer. Why doesn't matter but what happened next is entertaining. 

After we arrive at his house to get the booze we discover it is frozen. Obviously when this happens I call BS you watered this down. Not a big deal ppl do that. He denys it and tells me his freezer is just super cold. "OK I'll Google it" it turns out 80 proof alcohol freezes at -17 degrees F (-27 C). 

So the guy is obviously lying this is totally not a sub zero freezer.  Despite my showing him websites proving he is full of it he maintains his story to the bitter end, never really coming up with an explanation, just repeating that I'm wrong. Reddit has this ever happened to you? Do ppl commonly lie past the point of common sense or reason?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Ever have somebody lie to your face, you indisputably prove they're lying and they still won't admit it?
