Hey! 

Im new to the community, in fact im new to the numb3rs fandom!  I was watching this video on youtube http://www.youtube.com/watch?v=m5c_50BGGL8&feature=related  and i want to know what episodes these scenes are from...the one at around 0.10 when Don gets whacked on the head and the one around 0.27-0.36 where the guy throws some gas cans or whatever that is! Oh and 1.31ish..he looks so cute and sleepy heh!!

If there are any other whumpy don eps let me know too....Ive already watched the ep where he gets "shot" (a bullet graze rather...damnit!) and hot shot!

Ever since i roamed youtube for videos, i've wanted to know what eps these clips were from, its driving me insane lol  Im steadily watching episodes but there are 4 and a bit seasons to catch up on!


Edit:
I edited the post just for the clips request...im now going to check them out, thanks everyone who replied!!

I took out the fanfic request...thanks to VALERIEV84 i now have a good selection of don whump stories to look up!! 

I thought i had read the rules, but it was late when i posted so i might have got it mixed up with somewhere else...For ages i couldnt work out how to post to this community and then i realised i had joined another community instead and got myself all muddled up LOL 

thanks again everyone! Oh and thanks for being nice about my faux par mods...its nice to know i can post here again!! :D
