There's always going to be a first for everything. In this case, I witnessed a spider attacking a mouse--a computer mouse, to be exact.

So, here I am, minding my own business, when this teensy-weensy spider came crawling up my computer monitor. "No big deal," I thought out loud, "It's just a tiny spider." Except this spider was ruthless.

It spent a solid 20 minutes hanging out on the computer screen, following the computer mouse "arrow" wherever I moved it. It was to the point where it would jump on the pointer and try to attack it. There was no backing off for this tiny, yet fearless, spider.

That's when I pulled out my phone, and started recording the strange behavior of this minuscule, yet mighty, insect.
