/sci/ - Science & Math

Hey /sci/ can you teach me about contracts? I just watched that retarded Apple ToS episode of South Park where whatever bullshit they came up with was valid.
Like what if I signed a hidden paper contract that said I'm giving away my house like those movie/cartoon cliches where you didn't read the fine print.

Yo bro where do I get ahold of some pento barbiturates to kill my pet bear with? I heard they better than cyanide - no muscle spasm/convulsions, no carbon dioxide build up, shuts down all organs in 2-3 minutes.
Better than inert gas which costs a shit ton, requires a shit ton, needs an enclosure and can be sabotaged via even 2% oxygen interfering.
C'mon guys my bear is in pain. He's no honey badger who survives 200 bee stings and 2 king cobra stings.

What's the best way to kill a mammal? I heard of those injections they give dogs at kennels, what do they put in those things? are they painless?
