I haven't been fooled yet. I'm too aware.
But I pulled jokes on others.
I pulled a prank on my sister. I was making her a cd and so I told her I was gonna give her a copy of a band's new cd. She was all happy about it so she said yeah. However, as I made the cd I made the first two songs music from the actually album then the other 9 songs all annoying, stupid songs like the 'caramelldansen' and 'the fast food song'. I didn't label it and said I couldn't find the marker to label the cd, so she just took it. After she listened to the first two songs she suddenly heard the annoying ones and got really serious and told me "F*** you." However, she laughed right after. xd
As for my dad, I told him work called him to come in 5 hours early as someone called in. He started to go get ready at my grandma's house. I called him back 5 minutes later and said "April Fools. Nobody called." He went silent for a few seconds then burst out laughing as he shut the water off. xd
At least it wasn't the joke from years ago where I tied a creepy doll he hated on fishing string and hung it from the door. During that joke a few years ago, he turned white as a ghost. I got grounded for 3 months after that prank years ago.
