We're too old to have been fooled. We already knew that rattlesnakes don't have eggs so we knew it was a joke. The spring inside wasn't set right so it didn't make any noise. There was a note inside to put it back on the porch (I guess they wanted to use it again). I wish I had set the spring and tried it out before I gave it back.I hope it didn't scare you. I can't believe someone did it to a stranger since it can cause quite a scare!
