You have to have killed someone to get a killbug O_O.
I dare you... to hmm... get one and a half litres of water, pour it into a 2 litre empty Coca Cola/Pepsi bottle, and pour some old tea/coffee into the solution. Then stir it up, so it looks like real Coca Cola, and then add lots of random stuff into the bottle, so the person who you will prank will not see it. I did this in school with old Roast Potatoes like three years ago, didn't go down well with the teachers. I also put in ketchup, and a lot of other stuff like salt and pepper, but you could try all sorts of things, just don't try stuff like medicines, that will actually kill someone...
I sell the things you need to be, I'm the smiling face of your TV. I'm the Cult of Personality. I exploit you; still you love me,
I tell you one and one makes three. I'm the Cult of Personality. Like Joseph Stalin and Gandhi, I'm the Cult of Personality. Neon lights, a Nobel Prize, when a leader speaks, that leader dies. You won't have to follow me. Only you can set you free.
