When you live in New York, you get used to spotting celebrities just walking around and doing things like normal people.

One woman who spotted none other than Daniel Day-Lewis - on the subway like some kind of peasant, no less - found it difficult to keep her cool, but not for the reason you might expect.

As the photo she took will tell you, the Oscar-winning actor still uses a flip-phone, like it's 2001 or something. No fancy iPhone X here, no siree.

Of course, people are not at all surprised by this fact and have been sharing some amusing theories and explanations for why he might possibly be using such an antique (apart, of course, from just being Daniel Day-Lewis...)
