Get the Ol' Painless mug.
A fitting response to one who plans to give up the easy way.

Derived from M*A*S*H's haunting theme song.
"Man, I can't be bothered to study for this test, I'll just write the answers on my forearm. So what if I get caught."
"Yeah man, suicide is painless."

Get the painless steel mug.
An Adjective/Noun that means:
Lacking pain. If someone tells you something will be painless, they are likely lying, and the experience they are describing will usually be painful.
"Oh, come on! Getting stabbed with a 3-foot long needle will be practically painless!"
