But put hard life saver candies in their shower head because after they shower they will be sticky and not know why haha. Works every time they usually go back to the shower then come out even more sticky.
I did various things, cling filmed the toilet, put kool aid in the shower (ruined the shower head aha), reversed my mothers laptops background hid all the icons and the taskbar, (it did not go down well). I changed all my fathers account pictures (computer account, computer background, facebook picture etc) to a picture of an astronaut sloth, to further this I even covered over some pictures of my brother with this sloth. The best thing was printing of this picture
on my next-door neighboors wifi printer (I could access it). I then got a prompt phone call from a worried old woman. Great day!
