I've been watching HIMYM since its first season and am still in love with it. Wilfred and New Girl are my other two favorite shows right now.
Big bang and HIMYM are two really good ones! I also think Family Guy and Futurama are really good too.
Office is a great show! I really hate how the boss left the show :'((( Also scrubs was pretty good but I don't remember it much as I was young when i watched it.
