I am looking for a Comedy.

Just plain old stupid comedy, the only requirement is that the show was hilarious to you.

I generally watch most shows, but I've been really lazy at watching anime in general since i got close to finishing my undergrad. I really haven't watch more than a glimpse of most shows in the past year or so.
It'll be great if i can get some recommendations for gold that I might have miss in the piles of mediocrity.
Generally anything from the last 5 years are good choices since that was when i started to watch less and less anime.
