The loveable stoner

Typically the kind of guy Katherine Heigl will fall for (see previous slide and 'Knocked Up'), Seth Rogen has carved his niche as the unshaven, likeable loser with no ambition. On screen and in real life, Seth's the perfect guy to go for a beer with and, given his never-ending cascade of witty one-liners, makes a mighty fine wing-man in any bromance comedy (if he's unavailable for said role, Jonah Hill will step in as understudy). It's hard not to love the slackers played by Seth and, despite his wall-to-wall wardrobe of plaid shirts, you can always guarantee he'll score a girl much, much hotter than him.
