#1 Salt and Burn
Dean and Sam often salt and burn corpses and other items.
They do this to get rid of ghosts and spirits that are living beyond the grave.
#2 Mystery Spot
Aside from the other countless deaths in the show,
Sam sees Dean die numerous times in the Season 3
episode, Mystery Spot. This is the episode where he get
the famous Sam quote, "Yesterday was Tuesday, but today
is Tuesday too."
#3 Good Try
While this is a funny meme, it doesn't exactly make sense to us Supernatural fans.
In the show Supernatural, Sam and Dean do not use salt to hunt demons. They use
a demon blade, the colt, and other weapons, but never salt. Salt would only be helpful
when hunting ghosts.
#4 Life of Pie
Dean loves pie... What else needs to be said?
