I LOVE pratical jokes! My son does, too, and regularly sets me up. Some of my friends HATE jokes and pranks, so I'm careful about whom I target. This love for all things funny comes from growing up with LOTS of uncles who pulled fast-ones on me all the time. I associated these pranks with receiving positive attention, so it's all good!
This is one of my absolute FAVORITE youtube videos. I watch it once in awhile for a good laugh! It's truly, truly good!
