Have you ever heard my war cry?

.....disclaimer...if you are from PETA or you're a bit squeemish...this post is not for you...Quit reading right now!!!....

from a website...The second suggestion would be to check your math. It is not uncommon for people to exaggerate the size of a spider on first sight. If the spider in the tub is really the size of a tennis ball, like the one pictured here, there is good news. Your spider is most likely not the more dangerous hobo or recluse spider. It is probably a giant house spider (egenaria duellica) that can measure up to three inches in diameter with its legs extended.
The third course of action is optional, depending on the number and squeamishness levels of the household members. You can either call on the least squeamish household member (in order or bravery JENSEN, CHRISTIAN, TYLER)to deal with the problem, or you may already be the least squeamish member of the household. In that case, you can trap the spider under a glass, slide a sturdy piece of cardboard beneath the opening, and carry and release the spider in the outdoors.
Please remember to release the spider some distance from your house, or chances are he will soon visit again. House spiders rank among the speediest spiders on earth and yours may very well race you back home.

JUST YELL LIKE SOMEONE IS KILLING YOUR CHILD AND STEP ON THE SPIDER AND KILL IT!!!

First off...earlier today...I came into contact with yet another moving object...a HUGE (there is nothing small in my house) black beetle...I took a moment to gather my wits about me and decided that it was not moving very fast and that I would try and gather is up in a bucket and take it outside ALIVE...I don't kill everything in my house except if you are a spider, mosquito, or fly.  Ok, back to the story....I am the only one home...I was folding clothes in MY house and I put a shirt on a pile of clothes ready to be donated and I see this huge spider right as I was about to lay the shirt down...I picked the shirt back up and the spider moved.  GREAT!...I want to go and find the fly swatter because if I stomp on it now it will be on uneven ground and I will probably loose and I CAN'T LOOSE IT!  (I'm sure this is the spider that bit me a couple days ago...no it's not a mosquito bite...so I must end it's life)  I run out to the living room and try to find the fly swatter and I can't find it.  I run right back in my room to make sure he is still there...and he is.  I try to get the biggest bowl I can find to try and gather it up humanely like I did the beetle but it moved too fast and I was afraid that he move too fast around the bowl, I wouldn't be able to watch him and walk fast at the same time and open the door and throw him outside.  Besides...he'd probably be back inside in no time.  So I do the only brave thing I can think of.  I'm the only one home I CAN AND MUST do this!!  I grab the shirt and carefully start moving off the pile of clothes and onto the more flat surface of the floor.  I drop the shirt and the spider quickly tried to escape into some socks that folded on the floor...(gosh all this would be so much simplier if I didn't have so many clothes on the floor) and YELL MY WAR CRY and STOMP on the sock where the spider had hid.   Now I'm worried that I must know if I killed him and I don't want to unfold the sock in case he still alive.  I slowly unfold the sock and find that indeed he is dead.  I was relieved and promptly took him outside to take a picture of him.

 this is what he looks like alive (above)

 this is his nasty bite..the picture doesn't show as good as in real life...

And of course this is him passed on.
