What’s more psychotic is the fact he just doesn’t write the letters on one sheet but literally rewrote it each page. That’s funny as hell

[CommentPoster]

I like how going on a date is a "waste of time" for Dennis, but forging prescriptions, threatening women with a voice changer, and overall making this convoluted plan is totally fine

[glados]

Dennis laughing maniacally after scaring the girl from the payphone, then the camera cuts to actual Dennis laughing about the thought is hilarious.

[Vballnut]

"You're gonna wanna nurture her dependance now her car towed, or slash her tires"
Man that change of pace got me good

[tommyroelroel]

Dennis system never fails, because of the implication

[T.Ramby]

I think my favorite part of all this is how much Dennis seems to enjoy making the calls from the payphone.

[itsbrendannn]

“she thinks shes broken through my tough exterior from a man who is afraid to love, and then i slink out into the night” possibly my favorite line from this show

[duncanurquhart]

most underrated part of this bit IMHO is how unnecessary the system is, dennis is a reasonably attractive man who could easily have a casual relationship with any of these women but he still insists on ruining their lives so he can be in control

[xUnikronx]

"Pizzas good, youre the one thats good." Done deal!

[MercilusBeats]

"this is very emotional for her" is such an underappreciated line, cause it implies just how much of an emotionless sociopath Dennis really is hahaha. Amazing episode!

[aaronstark]

I love how Dee chides him for being a sociopath, but then we later learn that she has her own system which might be even darker than Dennis’.

[AlexAminoff]

Just seeing Dennis at a pay phone with that voice changer makes this whole
thing.

[llamapheonix]

This scene is 100% better when you realize that the actress is Glenn Howerton’s actual wife. Guess the DENNIS system really worked.

[julianarchy]

the best part of this whole scene is that he's explaining this while the bar is still open and there's patrons inside

[Eaterofeaterofpies]

"You're the one that's good" -flawless Dennis line

[masterzombie]

I love how years later the system keeps failing and Dennis so bewildered on why it doesn’t work. Then in season 14 Mac starts using it on Dennis.

[bandguy]

i just noticed how he slips out the window but her room is on the second floor

[glados]

I love how Dee tells Dennis that hes a complete sociopath, and instead of refuting it he just tells her not to interrupt.

[MBustos]

“Don’t interrupt “ is by far the best part of that bit and perfectly encapsulates how insane Dennis is and how much everyone hates Dee

[NotOnLand]

"It's very emotional, for her." such a great detail, calling back to his lack of emotions
