Excessive angst and unsubtle Tear Jerker moments can create Narm (we laugh so that we do not cry), and so there's a lot of inappropriate laughing when watching Supernatural.
- In the fifth season finale, Dean puts on 'Rock of Ages' by Def Leppard to break up the non-fight between Michael and Lucifer. It's especially funny because he trundles up in the Impala so slowly!
- In Season 6's opening episode "Exile on Main Street", the scene where Dean is lying on a bed while hallucinating that Azazel kills Lisa and feeds Ben demon-blood. Dean's desperate cries and sweaty face, the wobbly camera effect, and Lisa's "it's all your fault" are what really sell the hokeyness.
- Boss Leviathan Dick Roman's own personal form of You Have Failed Me, "bibbing". It should be horrifying, as he's essentially forcing his underlings to devour themselves. However, "bib" is just such a stupid word that it immediately kills the intensity of any scene it's uttered in. It doesn't help that the first time we see him do it to someone, he has his secretary dress them up with a handkerchief first.
- The Alpha Vampire's line "See you next season." It's exactly the wrong kind of meta, making no sense at all in-universe, and it isn't even followed up on the next season.
- The zoom-in on Crowley's face as he announces that there's an Angel tablet, which looks like it came straight out of the '60s Batman show. And it's preceded by Sam and Dean hurling themselves against the door in the most ineffectual manner possible as Cas simply mopes in the corner.
- Abaddon's death in Season 9's "King of the Damned". It tries to be a Call-Back to Sam's killing of Lilith as both a dramatic moment showing the killer's power and the killer's slide into darkness, but while Sam killing Lilith was dramatic because of the Internal Reveal and Lilith didn't look weak because they turned out to have had some agency in actually arranging it and masterminding it into happening as part of a Thanatos Gambit, the Special Effects Failure with Abaddon being lifted off the ground and the character looking worried without trying to run, attack with another weapon, or do literally anything other than stand there with their hand out in the time it took for Dean to become immune to their powers and come at them to kill them, made the killing of this ancient, badass, cunning Last of Her Kind look more silly than disturbing or awesome.
- In the Season 14 episode "Damaged Goods", Lucifer's former vessel Nick, who survived the archangel's death, has slowly drifted towards the darkside in previous episodes before he goes looking for Mary Winchester, who can lead him to the demon Nick is trying to track down. He does so by driving around in a friggin' rape van while trying to keep a low profile.
- Castiel's Dying Declaration of Love in "Despair" is kinda ruined by Dean's total lack of emotion, and the fact that it's followed by Castiel being dragged into the Empty turns it from an emotionally compelling scene into a fierce contender for the fastest Bury Your Gays moment ever made, making it rather uncomfortably funny to watch overall.
