[ten years later, the gang join Barney in his apartment as he looks to be on his death bed:]
Robin: You're too young. This isn't fair.
Marshall: We're not going anywhere, buddy. We're gonna stay here right till the end.
Barney: [weakly] Thank you, Marshall. [coughs weakly] Marshall, can I ask one final favor, my friend?
Marshall: Yes, of course, of course. Anything.
Barney: Eat this meatball sub.
Marshall: Wh- Where'd you get a meatball...
Barney: I don't have much time!
Marshall: Okay, yes, yes, of course. Of course. Does this have some sort of special meaning?
[The meatball sub explodes and covers Marshall's face in marinara sauce]
Barney: [guffawing] 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! [guffawing]
Ted: Uh, Barney, you got a little marinara on your pajamas.
