Jason Jordan Segel (born January 18, 1980) is a very tall and very funny actor and writer. He is best known as Marshall Eriksen on ''Series/HowIMetYourMother'' and as the lead in ''Film/ForgettingSarahMarshall'', which [[WrittenByCastMember he also wrote]]. He is also known for working with director/producer Creator/JuddApatow, most notably in the [[ScrewedByTheNetwork short-lived TV shows]] ''Series/FreaksAndGeeks'' and ''Series/{{Undeclared}}'', and the movies ''Film/KnockedUp'' and ''Forgetting Sarah Marshall''.

He starred in and wrote the 2011 film ''Film/TheMuppets''. Those who find this strange should remember the Dracula Puppet Musical from ''Forgetting Sarah Marshall'', which he also wrote.

He also co-wrote the Infant Sorrow music for the movies ''Forgetting Sarah Marshall'' and ''Film/GetHimToTheGreek''.
