He forgot the quotes, so I grabbed a few I thought were good. :)

    Aaron_Denney says: "Don't anthropomorphize computers.  They hate it 
when you do that."

    BMeph says [to psygnisfive] In #haskell, you can't hardly be taken 
seriously w/o writing a monad tutorial...

    heatsink says: @pl (\y -> you y off)

    taruti says: damn GHC. I had a nice example for a pretty but 
inefficient way to compute things and now the new GHC optimizes it to be 
fast ._.

    Japsu says: segfault cat is watching you unsafeCoerce
