Summarize this article in one sentence.
Use a real parking ticket as a template and change it to her name. Make the ticket very expensive. Include a note on what the ticket is for and make it seem plausible, such as when she ran a red light a few days ago.  You can then mail the ticket to her. Or you can pretend to find the ticket in the mail and give it to her that way. Make sure you tell your girlfriend that the ticket is a prank and not real, especially if she seems very worried. Say to her, "April Fools!" and rip up the fake ticket. Squeeze out her toothpaste and replace it with mayonnaise. Do this when she is sleeping or away for the day. Then, watch as she tries to brush her teeth with mayonnaise instead of toothpaste in the morning. Scrape off the cream in Oreos and replace it with toothpaste. Then, give your girlfriend a box of the fake Oreos and watch her eat one. Be careful that she does not eat a lot of the fake Oreo, as eating a lot of toothpaste can make her sick. When she sends you a text, respond with a message that says, “This number has been disconnected. Please contact your provider.” You can also respond with a message like, “Who dis?” or “I don’t have this number in my contacts, sorry!” If your girlfriend seems very confused by the message, you can send her a text that says "April Fools!" so she knows you are joking. Glitter bombs can be made by filling an envelope with glitter. Then, give her the envelope so she is showered in glitter. Do not throw the glitter bomb at her, as this can result in injury. Put a ring pop in a ring box and wrap it with a bow. Then, give it to your girlfriend as a gift. Watch her reaction as she pulls out the ring pop, rather than an actual engagement ring. This prank can be intense and should only be done if your girlfriend has a very good sense of humor. She may get upset at you for this type of prank, so do it at your own risk.

Summary:
Give her a fake parking ticket. Put mayonnaise in her toothpaste. Make fake Oreos. Send her a prank text message. Give her a glitter bomb. Create a fake proposal.
