At the beginning of every scene write where it is, and whether you are indoors or outdoors (Int. = Indoors Ext. = Outdoors). Stage directions are written in blocks of text spanning from the margin on the left to the margin on the right. Text is in blocks at the middle spanning from the center (imagine the page is split into three equal thirds, you would be writing text in the center). Always have characters’ names in capitals except within dialogue.
This is where you put the jokes in. Make them true to your character and to your style.
