嗝兒屁

儿 = 丿 + 乚 : Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king. Albert Einstein (Ø-) and Sun Wu Kong (儿) are fighting in the space station's kitchen (-Ø2). Their weapons: Albert Einstein has a shovel (乚), and Sun Wu Kong has a banana (丿).

屁 = 尸 + 比 : Pocahontas (pi) is trying on her new bikini (比) in the space station's bathroom (Ø4) but she can't stop farting (屁). At least she thinks she is, in reality an invisible ghost (尸) is farting all the time to make her think so and prank her.
