When your brain shuts down

Today one of my friends asked me "If you could choose one superpower, which one would you like?". But then the thing happens. As soon as I get asked to choose something, I suddenly forget every single thing I know. I forgot every single superpower, and the first one I could think of was invisibility. I panicked and said that. I still can't think of any superpowers that would be cool. Maybe the ability to refill things. No money? Refill. No food? Refill. No shampoo? Refill that bottle!
Well, that was a step aside. I don't know if anyone recognizes my trouble. Ask me to mention three presidents, and I forget every single president to ever have existed. Ask me what kind of ice cream I prefer, and I forget every single flavour I've ever tasted. I found a video that proved to me, that I'm not actually the only person to have this problem. In this video, a guy approaches different people and say "For a dollar, name...." I laughed really hard when I watched it, because I recognized myself in it. There's one person who succeeds, the rest are panicking and not responding. Watch it here:

Do you recognize it? Let me know!
