Perhaps my favorite How I Met Your Mother episode to date…Barney’s named gets changed to Swarley against his will.
Some of his names included Swarlhili, Swarles Barkley, and Swarles all given to him in various ways. My favorite being the phone call at the bar. Ted sits down at the table and starts complimenting Swarley on his suit. Swarley feeds into it and gets so excited until he hears his name being called by the bartender saying “I have an important call for SWARLEY! SWARLEY! You have a call!”
I love Swarley!
Also, another Buffy sighting had been made. Tom Lenk plays one of the coffee house employees during one scene.
