A lion, King o' the jungle, is lying on a glade snoozing. Then an elephant appears, jumping and whistling. He jumps into a bush, rustling and suddenly a PLOPP. The elephant comes out again giggling and laughing.
Next day, same place, same lion. Again the elephant comes along. Again he jumps into the bush, again a rustling, another PLOPP. Again he comes out completely happy and disappears.
Third day, all the same, the lion is already taken aback. After the PLOPP, he ask the laughing elephant: "Hey, what are you doing in that bush that makes you so happy?". The elephant replies, "Well, I rape monkeys.". The lion, "But, that's normal. Everybody here does that.".
The elephant laughingly answers, "Yeah, but yours don't burst!".
