A couple years ago for April Fools Day 2017 I did the infamous Cajun Filled Donut prank on my daughter Trinity.
I procured a couple hollow chocolate glazed donuts and filled each. One with ketchup and the other with mayonnaise.
It was a Saturday so my wife and i left the house early while Trin was still asleep. When we returned to the house I went in like a loving dad to wake Trinity and give her the donut for breakfast. She woke up and I handed her the the mayo filled one first. She bit in and the face that she made was so funny. After spitting it all out told her the prank was over and that I was going to give her the "real" one now... I offered her the second one filled with ketchup.
