Neil Patrick Harris (Barney Stinson) really loved spinning the wheel with Bob Barker in the episode “Showdown.” (Originally broadcast 4/30/07)

Alyson Hannigan (Lily Aldrin) still tears up when talking about the USC marching band at baggage claim in the episode “Three Days of Snow.” (Originally broadcast 1/19/09).
Cobie Smulders (Robin Sherbatsky) enjoys portraying Robin Sparkles, especially in the episode “Sandcastles in the Sand” (originally broadcast 4/21/08) in which she filmed a music video featuring Alan Thicke, James Van Der Beek and ’80’s pop star Tiffany.

Uber Canadian Robin episode! LOVED IT. There are a few but that is one of my faves. And of course, when Robin and Barney finally got together.
