Watch comedy shows/movies hours after having surgery on your chest. Seriously, don't do it. DAMN YOU BETTY WHITE!
I have a heart condition (which i've mention numerous times in the past). Last month, they installed a difibulator in my chest. It's like that thing on ER shows (the ones that go 'clear!' and they shock you) but it's the size of a pacemaker. Say if my heart stops, it'll electricute it and start it back up. So yeah, they made an insission on my chest. I could hardly even try and sit up for a while because it hurt so much. So laughing was probably a bad idea. It was also bad that my dad bought "The Hangover" afterwards. Only at selected parts, it hurt.
