Genshiken is a great series. Anyone who has been a manga/anime fan for a while should check it out. You may find something in common with one (or if the geek is strong in you) all of the characters. What tickles me about the series particularly is that I can pretty much draw a correlation between each main character to one of my friends. That makes this a series particularly close to my heart. Also, Ohno has huge titties and is a cosplay nut. Oguie is a grumpy little artist/closet yaoi fan. *sigh* It's almost embarrassing.
Here's some Sasahara/Madarame love for you.
It's an actual featured pairing!
uh---sorta.
