Get the Captain Obvious mug.
A phrase that is used to state that what the other person is saying is obvious.
"Captain Obvious, he's our hero! He's gonna tell you what you already know!"
2 men are walking together outside during the zombie apocolypse. Suddenly, a zombie leaps out of some bushes he was hiding in, and rushes at the 2 men. One of the men takes out a shotgun and blows the guy's head off. The 2 men watch in horror as he collapses to the ground, blood gushing from his neck. "Oh my goodness! I think he's dead!" One of the men say. The other man looks at him and says, "Thanks, Captain Obvious." Frustrated, the first man takes his gun and blows his head off. The second man falls to the ground, blood gushing from his neck. "Oh my goodness! I think he's dead!" The man exclaims.
