Why did we get the Microsoft turtle emoji in this comic?
Me when I get to the end of a series I like:
Liam (captured by bad guys): I deserve this. This is all because I forgot to feed my turtle, Sheldon, in kindergarten! He went to heaven, and now my life is bad! You happy, Sheldon?! We’re even now!!!
Theo (trying to find what room Liam is locked in) : Liam?
Liam: SHELDON?!

"WE?? No you are you and you are screwed. Don't drag me into this."
Curt green eyes narrow upon him and lips press into a petulant pout. "Yesss. I believe that WAS what I said." Yelena drawls out sarcastically. "You forget, you had HUGE hand in this too." She stands her ground. "Mr. Science and Math are always ANSWER."
SCREWED? Her? NEVER. Always.
Sniffing, she indelicately adds. "I believe, I remember YOU, being the one who said this plan was BRILLIANT. Foolproof, EVEN. Huh." She gesticulates broadly. "Where all the brilliance go?"
Her hand reaches out to snare on the scientists arm and she yanks him down with her. "TOO LATE. Already dragged." She grumbles, keeping him out of the path of gunfire. "Unless you fancy being shot full of holes. Think it pretty cool way to die." The truth was, whoever was after Sheldon's latest formula had hired some pretty dangerous people. Conveniently enough, it was the same reason Yelena was hired to watch over Sheldon and his friends.
"Got 'a plan?" She prods. "Any time now." She grumbles pulling him towards the hallway.
You know someone is referring to Jim when they call him "the guy who plays the moron on the big bang theory"
Just watched the big bang theory season finale
SHELDON NOUUUUUU
The Big Bang Theory Season 8 Finale.
I wanted to cry! Actual tears came to my eyes when Sheldon asked the question after the video chat with Amy ended! And now my mom and I have to wait until Season 9 to see if everything turns out okay. -goes and cries in a corner-
