Funny slice of life comedy

I'm looking for SOL's that are genuinely hilarious.

Ones I've liked:
Ichigo Mashimaro (Most hilarious series ever)
Honey and Clover
Kannagi

Iffy:
Nyan Koi
Baka Test (Although not really SOL)
Seitokai no Ichizon

Not very funny:
Lucky Star
Working
K-ON!
Genshiken
Minami-Ke
Manabi Straight

I know it's a lot to ask, but a show with impeccable timing for its jokes (Like Ichigo Mashimaro) would be ideal. Thanks.
