Change your name in your friend’s phone to Darth Vader after deleting previous messages.
Text them from your phone “Luke, I am your father.”
Anonymously text your best friend and act like you’re their secret admirer.
Text someone at 3 a.m. saying, “How do make cereal?”
Text- I want to tell you something about you and it’s really important.
Tell them- No it’s okay you’ll get hurt.
They will go crazy thinking about it. 😀
