狗屁不通

狗 = 句 + 犭 : This dog I will represent by a Great Dane (German: "Dogge", very similar to "dog").

Guy Fawkes (g) and the Grammar Nazi (句) are being walked by their dogs, a Dachshund (犭) and a Great Dane (狗), in the outhouse (ou3). Guy Fawkes and the Grammar Nazi are very interested in each other and spend a lot of time sniffing each other's butts.

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.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

通 = 甬 + 辶 : In front of the engine a pile of yongzhong bells were blocking the way. Tommy Turtle attended to the matter and cleared the way. He lined the bells up to two lines, put on his gladiator sandals and now marches right through this path screened by walls on two sides like a roman general.
