There's no self-less good deed - Phoebe Buffay

I learnt this from the cheesiest character in my most favorite sitcom F.R.I.E.N.D.S, not that I reflect upon everything she says, but this one in particular popped back out of my ROM (dedicated to dialogs from F.R.I.E.N.D.S.) a couple of days ago because of something I did.

I do not think all humanity could have been summarized so beautifully, yet obliquely, in just six words. As Phoebe puts it; if you do something nice, it makes you happy, which makes it selfish!
