One time i remembered, it was in Mystery Spot when Dean was hitten by the car ;)
But i don't yell often :)

In "Sympathy For The Devil", when Zach announced that Dean was Michael's vessel.

Yeah, that's why I watch Supernatural alone xD

When Sam was chocking Dean at "When the Levee Breaks" and when they killed the bitch of the bitches!!

YES i cant help it dramatic events have me talking to the t.v and computer all the time !!!!!!!!!!

at like every season finale the first time i saw them. i still yell at the finale of S4, because i havent seen S5 yet

There is a reason y i watch Supernatural. I yell, scream, laugh,cry, gasp and every thing in between.

well i'm pretty animated already add in something i'm passionate about and you have a recipe for craziness

There are many reasons to scream at my TV when I watch SPN!!!!The plot is so interesting and captivating that I find myself yelling at the TV!:D

I did yell abuse at Sam quite a few times ;P

I'm almost always yelling at the tv when waching SPN!!!

Just about every episode. :3
Especially the s4 finale. O.o I practically couldn't talk the day after that. xD

yea me 2 ...i always do thats y i watch it alone.. but still every one hear me lol.. Especially in s.5..and the last episode of s.4 i yalled my voice out on ruby,,still hate here..

when they killed Ruby!!

i gasp & cry more than i yell and screem though =P
also laugh. i laugh a lot!

I gasp and cry and laugh and everything else too!

In Mystery Spot, when Dean died the first time, I gasped. The second time I gasped and then I got used to it and laughed. Because it was so weird. I never yell, cause that would be weird. And I'm not a yeller either.

Actually, I'm yelling at Sam and Dean to look out or to stop being an a**h*l, but whatever, I guess it's all the same thing.

NO... not when the killed her!!!!
when she closed the door so dean wont get in and stop her...
and when she was so happy 2 free lucfer from hell**freaky bitch**

I yelled very loudly at Sam every time I saw him with Ruby...ugh. And I yelled again at Dean whenever he passed up an opportunity to make a move on Jo, haha.

When I watch supernatural I'm very emotional...I mean very!!! I feel for them, I lough with them, I cry with them and I fight with them!!! I try to realy understand what they are going through!!!

i don't usually but this week i did !
