Uh no. I'm paid to do it, so it's what I do. I get more of a thrill when I'm explaining a system or concept to someone and I see the sudden realization on their face that they understand.
vikingfan, thank you :)

It is very impressive to see if it is very humid or a little foggy out as the moisture in the air causes a visible arc as the connection is broken. Lots of Snap, Crackle, Pop.

You're thinking of a disconnect switch. They are used to isolate unloaded equipment like breakers, and they can take switching on and off the energizing current of transformers & power lines. Switching power lines or transformers can make them sizzle quite a bit.
Load break switches can switch reactors and capacitors on & off. They have vacuum or SF6 interrupter bottles inside an insulated bushing on one end.
None of the above can interrupt major loads, nor interrupt a short circuit. That's done by circuit breakers that are either oil filled, SF6 filled or air blast breakers for something like the main generator breakers at a power plant. The oil filled or SF6 breakers don't do anything spectacular except for make some noise when they open and close. The air blast ones are very loud.
