My other favorite thing to do is pretend to be an expert in something I have absolutely no knowledge of. Like that one time I tried to give a 5-year-old a lecture on quantum physics. The look on their face when I explained wave-particle duality was priceless.
I'm not saying I'm a genius, but I'm definitely a Quantum Physics For Dummies kind of guy.
I've also been known to Pretend to be a Gourmet, mostly by ordering takeout and pretending to be a food critic. My review of the pizza place down the street? One star. The crust was too crispy.
Pretending to be an Artist is another favorite pastime of mine. I've been known to whip up a mean Impressionist with a can of spray paint and some hastily applied stencils. My masterpiece, The Scream, has been well-received by my mom.
And if you're feeling particularly adventurous, you can try Pretending to be a Time Traveler. Just don't tell my wife, she's still trying to get me to use a calendar.
