Deadpool Vol. 9: Institutionalized
After the fallout - nuclear and otherwise - of the Merc with a Mouth's antics in Arizona, the government is faced with an impossible question: what to do with Deadpool? Luckily, Deadpool's gamma-powered legal defense team provides an answer: stick him in an institution! When you think about it, it might be the only solution - after all, he really does need some professional help...as well as protection from the enemy: himself. Collecting DEADPOOL (2008) #40-44.
