Yeah, I do all the time. Mostly at the NEWS though.
"No Reese, your mom is just gonna spank ya in front of the school." - Me watching MALCOLM IN THE MIDDLE if you can't guess.
" Clare...Your kinda stupid. " - LOST
On video games I usually don't because well I like games like Oblivion and Fallout. ( Games that set the character as you ) But in these games I talk to other people in these types of games. *kills someone* "Hey, my sword of AZAROTH really works, thanks buddy."
One day I was playing Final Fantasy VII and I was like " YAY, you finally died Aerith, now I don't have to concern the death of YOU in real battles."
