That final gif is just pure magic...
I have a great respect for bowel twisting foulness, when someone smells something vile and accuses me of it while I'm not the culprit I'll always respond with "If I'd produced that, I'd have made damn sure you knew it was me, that's a fart to be proud of..."
I was going to make a joke about experiencing your friend's back passage first hand but then stopped, thought... after the laughter died off I thought best to make a joke about the joke ;)
I'll leave you with... Da-shiang bao-tza shr duh lah doo-tze!
Just wanted to let you know I'm coming back for a quality reply. Phone. So. Dead.
Fucking SHINY! I love meeting other browncoats! (By the way, I got my grandma into Firefly and they aired Serenity last night. She called me crying. :D)
Seriously, gut wrenching farts are a thing of beauty and pride. More people should proudly exclaim:
"That's right! Twas I!"
And carry on, I greatly desire this joke.
