Basic Trope: An expressionless expression of surprise or other emotions at something extremely surprising or shocking.
- Straight: Sam was a helpless witness to the murder of his family. However, at the sight of this horror he has shocked, but he has a bored expression.
- Exaggerated: Sam's life became the solid Deus Angst Machina, but he's still with his stone, unemotional facial expression, despite his pain.
- Sam in the middle of a hot battle under heavy machine gun, rocket, mortar and tank fire during the war, did become witness the apocalypse, he is tickled, has become Weirdness Magnet, he's being held hostage with a gun to his temple and/or doomed to And I Must Scream. Sam is shocked by all this, but he talks about his impression with a muffled, monotonous voice and a half-asleep expression on his face.
- No matter how much is he impressed, angry, delighted, etc. Sam is always with a blank, half-asleep expression and deadpan, casual, monotonous tone.
- Whole the cast reacts to everything like that.
- Downplayed: Sam is only mildly surprised, but it's quite insignificant.
- Justified: Sam is played by a bad actor.
- Sam is robot or alien.
- Sam is The Stoic.
- Sam has a facial injury or paralysis that prevents him from expressing emotions.
- Sam has some kind of disorder that prevents him from expressing emotions normally.
- Sam is experiencing something really so fantastic that it is even difficult to express it.

- It's just a lot easier for Sam without Chewing the Scenery.

- Or he's Chewing the Scenery.
- Parodied: ???
- Averted: Sam reacts to everything the same way as the rest of the cast.
- Zig-Zagged: Sam's reactions vary in intensity they are both dull, normal, and excessive.
- Lampshaded: "Sam, someone else in your place would have been crying/shouting/swearing/laugh"
- Discussed: "There is a war with aliens on Earth/there is an armed raid at Sam's house or at work/someone is tickling Sam/Sam got cancer/Sam is doomed to Fate Worse than Death, but Sam unemotionally-deadpanly meets/looks at it, it's unbelievably"
- Exploited: Sam was dull-surprised, that he may be glorified for his composure and stoicism.
- Played for Laughs: Sam is the Extreme Doormat, who is ready to unfazedly accept any absurdity.
- Implied: "Sam reacts to something amazing/scary/funny/tragic emotionless although it's causes a more emotional reaction in others"
