In one sentence, describe what the following article is about: Scions should be up to three dormant, or not currently sprouting, twigs of about a foot long containing three to five buds. Don't cut scion and rootstock at the same time.  Rootstock should be straight, smooth, vertical branches 1–2 inches (2.5–5.1 cm) in diameter. Bark grafts should be performed once the rootstock bark has begun slipping (when the bark is easily peeled off in spring). This graft is usually used for instances in which the rootstock is too big for whip grafting. Above a crotch out of which several branches grow, cut straight across one branch with a very sharp saw so as not to crack or rip the bark or wood of the branch. Make sure you leave a branch nearby to keep nutrients moving up the tree. Cut the scions down to around 5 inches (12.7 cm) in length while still retaining about 5 buds per scion. Around three inches from the base of the scion, make a sloping cut inward until you reach the base. Hold each scion up against the rootstock so that about 1⁄8 inch (0.3 cm) of the cut surface of the scion shows above the rootstock. With a sharp knife, outline each scion on the rootstock. Remove the scions and finish cutting away this bark so that each will fit snugly into its space. Place each scion in its space on the rootstock, taking special care to ensure the green wood of both parties aligns exactly. Once in place, hammer two wire nails into each scion to hold them into the tree. Pour grafting wax or asphalt water emulsion over the area to seal all cut surfaces from drying and bacteria. Check the seal again the next day to make sure no holes have formed. Keep removing all growth below the graft. Once one scion shows more promise than the other(s), leave that one as is while pruning the less successful graft(s). Two summers after grafting, remove all but the strongest scion.
Summary: Choose your cultivar and your rootstock. Amputate the rootstock. Prepare the scions. Prepare the rootstock. Introduce the scions. Seal the graft. Look after the graft.

Problem: Article: Use dialogue to add humour to a screenplay. Have witty back and forth between characters. Have one character who is full of funny one-liners. Create running jokes that are said throughout the screenplay by different characters. Dialogue gives you a chance to have your characters tell jokes to one another and be witty. For example, you may have one character who uses a signature catch phrase and tone of voice to say their dialogue, creating humor. Develop a character over a long period of a time in a novel so they become endearing, witty, and funny to the reader. Give them a funny childhood or a unique sense of humor. Let the character's voice and actions come through as the novel progresses and add in funny or amusing details about the character. The reader will then get a sense of humor from the character. For example, you may have a character who seems minor in the story but always has a funny aside. You may then have them become more important as the novel progresses, putting their humor front and center. The element of surprise can be a fun way to jolt your reader and make them laugh. Have a plot twist in the play that you find funny and surprising. Keep the viewer guessing and use the element of suspense to create surprise and laughter. For example, you may have a big reveal 3/4 of the way into the play where a character turns out to be a woman dressed as a man. You may stage the reveal so it is funny and surprising for your audience.
Summary:
Emphasize comedy in screenwriting with dialogue. Use long-term character development in a comedic novel. Surprise the reader in a comedic play.
