Toilet toilet humorous ancient poetry couplet stool drowning

Toilet couplets generally have the meaning of joking and teasing. For example:

Shit falls into the pit and shakes the stars for nine days;

Urine shoots at the toilet wall and spews out of the Yangtze River.

Give me another teasing poem about toilets:

Report to the commander that the enemy plane is coming. Sweep the machine gun first, then fire. Put up another poster after the battle.
