After Ellison accepts his offer to help with the investigation:
Ellison: There are a few things you could do for me actually. [...] Do you have a notepad? Deputy So-and-So: Uh ... *beat as he rummages through his pockets* Yes! Ellison: Do you need a pen? Deputy So-and-So: *another beat* Yes!
Really, most things So-and-So does in the first film are either Adorkable or hilarious, or both.
After seeing the dog, Ellison tries to keep it calm while slowly reaching for his bat.
Ellison: It's all right... I won't hurt you... I'm just going to grab my bat... so I can bash your head in... if you come near me.
After Tracy realizes why Ellison moved them into the house:
Ellison: It's not like somebody got murdered in that bed!
The 'shush' gesture plus the Kubrick Stare that Bughuul's children give in the extended cut of the reels can be silly after seeing it for the first time.
Sinister 2
When So-and-So arrives at Courtney's home with the intention of burning the house down to end the cycle: he comes in all badass, with gritty music playing in the background and while carrying gasoline containers. He then gets interrupted by a squeaky toy he steps on. Cue him saying “What the hell ...?
It gets even funnier when he sees Dylan staring at him, eating an apple, all while So-and-So realizes how awkward it's become.
So-and-So: Uh ...
The continued awkwardness of So-and-So's confusion by Courtney's outbursts after she finds him on their private property, thinking he's involved with Clint. It looks like a John Cleese skit.
