Ironic quote of the day

From Rick C on my Andreas Moritz post.

I bet you could count your friend on less than half of one hand, and when it comes to pleasantry you have less than 1000th of a brain. Back Off with your foul abuse

Is is possible to count a single friend on more than “half of one hand”? And what constitutes precisely half of a hand? Does Rick C have half of a finger? Does he not use fingers for counting? How does one measure pleasantry in terms of the brain? Does it go by mass or volume?
