Barney: [speaks alien language]
Future Ted: [v.o.] Over the years, we'd seen all sorts of levels of Barney's drunkenness.
[flashbacks to Barney at MacLaren's:]
Barney: How you doing?
Future Ted: Richard Dawson drunk.
Barney: Is this your sister?
Future Ted: "Big plans with strangers" drunk.
Barney: Hey! Me and the Road Dawgs are going splitsies on a time share in Flint, Michigan. And non-refundably booked. Come on, I'm gonna buy you all some mopeds. Road Dawgs!
Future Ted: And Marcel Marceau drunk. But we knew the night was over whenever Barney got Jabba drunk. So drunk that his speech bore an uncanny resemblance to that of... Jabba the Hutt from Return of the Jedi.
