Mine aren't this little anymore, but I just had the most fun messing with a 3 year old. The wife was opening the oven door and picking bits of stuffing off the turkey and her niece's 3 year old son wanted to see the bird in the oven. I wondered how he'd react and I just couldn't resist the fun....
.....I quietly slipped out to the garage and dug into my turkey hunting gear. I retrieved a gobble-shaker call and positioned myself next to the oven. When this little boy wasn't paying attention I let out a thunderous gobble and he jumped up from the table and turned to see if that bird was trying to get out.
Grandma then helped with the charade. She would block his view of me next to the oven while she opened the door so they could take a small peek inside - <another booming gobble>.
He's convinced that bird is still alive. .....And it's gonna' gobble one more time just before we eat it.
