Kare Baka: Wagahai no Kare wa Baka de R

Surprised no one has made this recommendation yet. Both anime start off the same - an average looking high school girl, under pressure from society/friends for being single, lies to her "friends" about her boy friend, who coincidentally is an extremely handsome man. So while everybody goes gaga over him, only his "girlfriend" knows the truth about his true nature as a person. However, while Kare Baka is a mindless comedy meant for shits and giggles, Wolf Girl actually has a story that moves forward, with the biggest focus being on the developing feelings between our MC and her fake boyfriend. 

They both have that quick slapstick comedy with ridiculous plot development and the overall theme of idiocy in a comedic way. Overall danshi koukousei was better because it had more attempts at developing a plot, but they're both pretty fun in their own way.  

Having to deal with an idiot friend/boyfriend, is not easy for the protagonists of these two series. Aho Girl and Kare Baka are anime about the everyday life of an idiot girl/boy, and most of the jokes revolve around that fact. They are both short anime and the comedy can be pretty similar and funny.
