My favorite is probably in my sig:
"having a proper education system is irregardless of drug use."
It's just so wrong on so many levels. In its original context, it was meant to be an intact sentence -- I didn't cut it out of another sentence. So features a lack of capitalization, the ambiguous use of the word "proper", the non-word "irregardless" as well as being largely incomprehensible. Then the statement is compounded with the irony that the person writing it was obviously a product of our completely dysfunctional education system, yet they feel so uninhibited to provide commentary on the educational system. Now stop an think about how you could do that in a mere 10 words. That's not as easy as you'd think. I guess its a poem of sorts.
