Do you ever remember a face but can't for the life of you remember what that person is called? Well you aren't alone in that aspect as it is a very familiar feeling when it comes to sitcoms that have amassed a vast cast. How I Met Your Mother is the perfect example of a show that will re-kindle that feeling.

We are all very familiar with the couple that set the standard for all couples in Lily and Marshall, we have all been with Ted on his relentless quest to find the one true love of his life, we have bore witness to the maniacal masterpieces displayed by Barney in the name of bedding women and we have discovered the many mysteries behind the walking piece of Canada that is Robin. But what about the not so obvious characters that pop up now and again?

Through the nine seasons of the show the gang have went consistently from one hysterical moment to another ludicrous scenario, not just impacting their lives but of those around them.

How many of these following characters do you think you can name? Bet you can't name them all!
