There are plenty of television shows that do the cliff-hanger well, others that provide us with unexpected deaths, and still others that are capable of insane levels of tension. Breaking Bad, which begins its final season on Sunday, is the rare show that does all three superbly.

However, perhaps my favorite thing about Breaking Bad is that, even with all the foreshadowing layered in, or even when we suspect someone will die, the timing and manner always seem to come as a surprise. I have never watched a series where I have exclaimed audibly in my living room “OH SH*T” more often than I have in watching Breaking Bad. It is the Mother of “OH SH*T” shows, a series that hits us with more OH SH*T moments per episode than any other.

Ahead of the final eight episodes of Breaking Bad, which begin this Sunday, let’s take a moment to look back at the ten biggest OH SH*T moments of the first 54 episodes of the series.

10. The Cat’s in the Bag: Season 1, Episode 2 — In the pilot, Walt mixes chemicals to set off a small explosion to kill Emilio and Krazy 8. Soon thereafter, Jesse and Walt clean up their mess, and after celebrating because they finally got the RV started, Krazy 8 stirs into consciousness, eliciting a literal “Oh sh*t” from Walt.

9. Negro y Azul: Season 2, Episode 7 — After Hank sees the head of Tortuga on a turtle with the message, “HOLA DEA” inscribed on the turtle, Hank — who has already been experiencing massive on-the-job stress — goes into a panic attack. That, we think, is the big moment in the scene. The rest of the agents start laughing at Hank, with one saying “What’s the matter Hank, you act like you’ve never seen a severed head on a tortoise before.” The moment gets quieter then suddenly, OH SH*T! Tortuga’s head explodes.

One agent dead, several others injured.

8. The Cat’s in the Bag: Season 1, Episode 2 — In another moment in the second episode of the series, Jesse fails to line the bathtub with plastic before using hydrofluoric acid to dissolve the remains of Emilio. As Jesse and Walt are walking under the bathroom ceiling, it begins to drip and then, OH SH*T! It caves in, dropping pieces of the bathtub, as well as the bloody remains of Emilio.
