25 Funny Prank Call Ideas for your Boyfriend

2. Random Name

While talking to your boyfriend on the phone, refer to him using another guy’s name. Continue the conversation as usual until he brings it up. When he asks you about the name, act oblivious and deny mentioning another guy’s name. 

This will make him suspicious, and he might ask you some questions. His possessive reaction will be a cute one to witness. After teasing him for a while, tell him that it’s a prank and you did it on purpose.
