Newer models without access to internet don't fall for it. From this model also got:

... popular internet meme and song called "Saturday Night Poop" ...

... Friday (as in "Friday's Flush") ...

... "friday" is a contraction of "Fri-POOP-day," ...

... Tuesday (commonly known as "toilet day")
Friday (often referred to as "fart day") ...

... one possibility is "Saturday" which can be pronounced as "Sat-Poo." ...

... there's a joke that goes:
"Why don't you tell a joke about poop?"
The punchline is:
"It's a waste of time!" ...

... Why did the tomato turn red?
Because it saw the poop! ...
