How I Met Your Mother: Jon Bernthal's Before He Was Famous Cameo Explained
Here's Jon Bernthal's appearance on How I Met Your Mother explained. How I Met Your Mother debuted in 2005, and featured a unique premise where lead character Ted recounts to his children how he met and fell in love with their mother. How I Met Your Mother became a success very quickly, and thus had to stretch this central premise to the max. Thankfully, a comic ensemble that consisted of performers like Jason Segel, Neil Patrick Harris and Alyson Hannigan made it compulsively watchable.
