Comedy

also , not every joke needs a puch line.some can be extended jokes or thing you expect to be like normal jokes but arent

also people forget about timing and other things leading up to joke .
some people think its funny when i type rude things just because i usually dont act like that and they dont expect me to so it suprises me they find something so simple as funny. i thought they were being mean at first and they think im like a baby but now i realise they just dont expect it from the way i act
