"Taser" is one of those words that's actually an acronym. Technically you should write it in all caps, like you're screaming -- maybe screaming like a guy who doesn't want to be tased, bro. It was developed back in 1969 by a fellow who worked at NASA. And because nerd stereotypes have to be ironclad, the name came from one of his favorite books, a 1911 sci-fi novel.
The term stands for "Tom Swift And His Electric Rifle," which you'll notice should be TSAHER, or at the very least TSAER. But that doesn't sound like anything, so who gives a shit? A fun side effect of this story, of course, is that if you yell "Don't tase me, bro" at someone, you're apparently yelling "Don't Tom Swift and his electric rifle me, bro!"

"Sony" Is A Bastardized Version Of "Sonny"
If you're ignorant like me, you assumed "Sony" was like the last name of the CEP or something. Maybe it's the Japanese word for "Walkman." But enough with the speculation, because it turns out it is neither of those things.
The origin of the name "Sony" is far dumber than it has any right to be. The most reasonable part is that before Sony was Sony, they manufactured audio tapes called Soni-tapes, which came from the Latin word for "sound," sonus. That sounds legit, right? "Sound," "Sony." No problem.
But there's a second layer to the name. The CEO of Sony was looking for a name that conveyed "youthful energy and irreverence." And what better way to do that than with the English phrase "sonny boy"? Thanks to the way the letter "o" is pronounced in English versus Japanese, the "sonny" aspect was lost in translation, and Sony gets all its youthful vitality from a nickname last uttered by an old-timey prospector trying to warn off a claim jumper.
