Future Ted: [v.o.] That night, as I worked on a new design that just might solve all my problems, Marshall was visited by a disturbing vision.
[As Marshall and Lily kiss in bed, he imagines Lily and Robin sitting in the corner talking about his sexual prowess:]
Imaginary Lily: Ugh, he thinks I like this... But it feels disgusting.
Imaginary Robin: Uh, it looks disgusting.
Marshall: Um... Uh, is this working for you?
Imaginary Lily: "Uh, is this working for you?"
Imaginary Robin: Oh, of course, because what woman doesn't like being slobbered on while some giant paws at her nether regions like Lenny from Of Mice and Men?
Imaginary Lily: Oh, you're bad.
Imaginary Robin: More Cosmos?
Marshall: I can't... I can't do this! I can't stop thinking about you and Robin!
Lily: Oh, I've had that a couple times. Just lean into it and let it fuel things.
