I'm actually one of the worst BSers in the world. It's impossible for me to keep my poker face. I normally crack a smile or get completely flushed. Especially if someone questions me a second time, I usually crack!
I don't remember when it was exactly that I had convinced people of these random facts, but it was during our undergrad at Rutgers. Just to be nice, I'm not going to tell you guys
who were the ones that actually believed me. It was 3 things that I got people to believe me for (well until I cracked or days had passed) - involving a butterfly, ATM, and left-handers.
Do you know the Jamaican butterfly? I convinced others that it resided in Jamaica (er duh) and that it's actually the size of a human being. Oh yes, a butterfly the size of a human! How freaky is that?!?
Since I spent so many years working in a bank, I should be very knowledgeable of it all. Somehow the subject of ATMs came up. I explained that it stood for automated teller machine. I told them that back in the day when ATMs first came out, it wasn't as high tech as now. In fact, they used to have an actual person sit in the back of the machine, who would slip the bills out to you. There was some doubt, especially around the fact that the machine seemed too tiny to host a person inside. That wasn't a problem since the other end of an ATM is sometimes in the vault. That way, the person wasn't really sitting inside the machine that you saw, they were just behind it.
I must say the best fabrication was when I pulled out my psychology facts and experiment results! I had a lot of people convinced for a long time about an interesting study about left-handers. I explained that recent studies had found that left-handers engage in self-loving more than right-handers. I can't remember what backings I used, but they were good ones. After a few days, I felt bad so I told them that I made the whole thing up.
