How I Met Your Mother, Season 6

[The gang sees Barney at his deathbed in 2021]

Robin:
You're too young, it's unfair!

Marshall:
We're not going anywhere buddy, we're staying with you right up till the end.

Barney:
Thank you Marshall. [coughs] Marshall, can I ask for one final favour, my friend?

Marshall:
Yes, yes, of course, anything.

Barney:
Eat this meatball sub. [offers wrapped sub]

Marshall:
Where did you get this-

Barney:
[winces in pain] I don't have much time!!!

Marshall:
[unwrapping sub] Yes yes, of course, of course. [prepares to bite] Does this have some sort of meaning? [meatball sub explodes in his face]

Barney:
[gets out of bed and laughs menacingly] I'm not sick, you idiots. I've racked up $30,000 of uninsured medical bills for symptoms I don't even have. Totally worth it! You should see the look on your face. Oh, wait, you can't-- 'cause it's covered in marinara sauce!

Ted:
Uh, Barney, you got a little marinara on your pajamas.

[Barney looks at his pajamas and stops laughing; his face decomposes itself]
