The very very end of S1:E12. You don't hear or see actual v, but a character says "5 bucks he throws up again" and then Dennis puts his face in a trash can. Very easy to skip, just end the episode when they say "Dennis will be a good dad."
A character says "what, do you have Asperger's or something?" The other character later explains that he is on the Autism spectrum and that word should not be used.
words like crazy, insane, jerkface. also an autistic character is called a man baby for having needs by the main character. there is also someone in the office is supposed to be very weird and gets treated that way.
