Drinking From the Punchbowl

Thanks to a little comment coaxing from fling, I've decided to give the Punchbowl Meme a go. It asks that you write a four-line poem where the first and third lines read "Turd in a punchbowl". The second and fourth lines can be about anything, but they must rhyme. Here is my attempt...

Turd in a punchbowl
One cup won't make you sick
Turd in a punchbowl
But two might do the trick

Turd in a punchbowl
With three you're on a roll
Turd in a punchbowl
If barfing is your goal

Can't you just see this on a bathroom plaque (in somebody else's house)? The words would be in cursive and there would be an illustration with puffy clouds, blue sky, a bird and a punchbowl.
