What is the funniest prank you played on someone or they played on you?

I came home from lecture one day and realized my mom wasn't home so I took this opportunity to freak her out. She's really into paranormal shit btw.

I regularly go have lunch with my dad and he'll sometimes pick me up. So I told her that I was going to eat lunch with him and that he picked me up in order for her not to get suspicious that my car was still there. After I got off the phone I set the house alarm and locked the doors like I was gone. I then hid in her office. In the corner turned away so I'd be facing away from her and she'd just see this figure in her peripheral vision and freak out.

My plan turned to shit when she got home and didn't come back to the office. She stayed in the kitchen. Well in our kitchen is our front door and side door. Next to the front door is a bathroom which leads into another room and that room has a hallway which leads into the laundry room which is connected to her office. So I'm quietly walking all throughout the house because we have creaky wood floors. I get to the bathroom, which was tile, and give a sigh of relief because I no longer have to worry about noisy walking. This is were I started recording everything. I then walk slowly into the kitchen. Our counter faces the side door and I'm right in front of the front door just standing there recording.

I realize she's not looking up so I start swaying around to kind of give a creepy vibe. She then went to close the mayo and at the second I knew she was scared because she paused and was looking out the corner of her eye. She slowly raised her head and said "oh shit!".

I think that's the most I've ever scared someone and probably the most I ever will.
