at home we have i guess you could call it a joke involving a plastic spider about the size of my palm this spider a red-back i believe is placed somewhere on top of a door so it'll fall on the next person who opens it and the whole thing is a bit of a competition of who can not be scared when it falls unexpectedly onto them, then put it somewhere where it'll fall on someone else
right now i believe its perched on the shower head i didn't put it there i spotted it out of the corner of my eye i hope i don't forget it's there when it topples onto me
