What is the J point?

"Did you know there is a pop tart under your fridge?
No, but dips."

If you've ever watched the TV play How I Met Your Mother, you should know this line which is stemmed from the scenario that Marshal and Lily get up from the kitchen floor.
( "pop tart" is a kind of cookie and "dip" is a kind of condiment, right?)
But what is the HHP here? Why does the director or someone else make this scenario go with the background of laugh? I think it's literally funny. The only reason why I didn't laugh is that I get the wrong words here. So could you tell me what correct lines are here and what J point is?

I have no idea what HHP means. I only connect "J point" to reading electrocardiograms.

Eh... Maybe you've not gotten the point of my post. I mean what the J point of the line is.

 

[MikeNewYork]

I definitely have not gotten the point. What did you mean to ask?

 

[Tdol]

What do you mean by HHP and J point?

 

[SoothingDave]

It's not "dips," but "dibs."

Marshall (I presume) is claiming ownership (or the right to possess the "found item") of the Pop Tart. Since it would be incredibly gross after being under the fridge for who know's how long, that is the source of the humor.

A few notes:

It is a TV show, not a "play."

"Pop Tart" is a brand name and should be capitalized.

Nobody here knows what "HHP" or "J point" means.

I was bored so I spent 5 minutes inventing meanings for HHP and J point.

HHP = Ha Ha Point = The point at which the audience is expected to/meant to laugh.
J Point = Joke Point = The punchline or "Why it's funny".

Sorry, they were the best I could do. I've never heard of them. Nothing comes up on Google for these to do with jokes or sitcoms etc and, as you've seen, no-one here has heard of them.

First, you should have watched the TV play how I met your mother, particularly the first episode.Then, pay attention to the line I quoted.
OK, actually, my question is why you guys laugh at this line when they just talk about something under the fridge. Based on the same logic of human beings, I think I can understand the reason why everyone laugh, unless the situation is a kind of something about culture or even I get the wrong line.

Eh... I specially search this phrase to make everybody here get better understanding of my question.

Do you mean claiming ownership of the incredibly gross tart is humorous?

no-one here has heard of them.

Perhaps only the Chinese have heard of them, according to the following.
'HHP is a popular online abbreviation for “haha point”. "Haha" is an echoic word for laughter in Chinese and "point" is the Chinese equivalent of "threshold." Therefore, haha point refers to the threshold where you can be amused and burst into laughter.'── quoted from http://www.suxuewang.com/parents_article_view/8653.html

Not a teacher.

Got it! Thank you so much! Originally, I just want to make a colloquial post, although self-defeating at last...
