Believe it or not, HIMYM aired 10 years ago today on Sept. In honor of the beloved show's anniversary, I've decided to round up the most legen—wait for it—dary guest stars.
Because as much as I will always have a special place in my heart for Ted Mosby, Lily Aldridge, Marshall Erickson, Barney Stinson, and Robin Scherbatsky, HIMYM would have been super boring without these wonderful cameos.
