Bathroom walls - the ultimate message board?

I’ve seen that at various workplaces as “Push button for latest Union hotline.”

Here’s another approach to improving those electric hand-dryers that I’ve always enjoyed: http://www.signnation.com/wp-content/uploads/2014/05/receive-bacon-1024x576.png

Thats funny!

“Those with shorter bats please step closer to home plate”

Willy was a scientist but now he is no more
what Willy thought was H20 was H2SO4

I always heard that as “Little Willie.”

Alas for Little Willie.
We shall not see him more.
For what he thought was H2O
Was H2SO4.

Some more Little Willies:

Little Willie lit a rocket
Which his dad had in his pocket.
Next day Willie told Cousin Dan,
“My daddy is a traveling man.”

Willie saw some dynamite,
Couldn’t understand it quite.
Curiosity never pays;
It rained Willie for seven days.

Little Willie, quick as flashes
Fell in the fire and burned to ashes.
By and by the room grew chilly
But no one dared to poke up Willie.

Little Willie from the mirror
Licked the mercury off
Thinking in his childish error
It would cure his whooping cough.
At the funeral, Willie’s mother
Smartly said to Mrs. Brown,
“Twas a chilly day for Willie
When the mercury went down!”

I spotted one of my favorites in a Cal men’s room years ago:

Mike F. - Class of whenever I get enough credits

And some decades ago, when there was an upsurge of radical Welsh nationalism just at the same time as a rash of promotional gifts by fuel companies, graffiti reading

FREE WALES!
would soon be completed by

- with every gallon

In a Northeastern U commode stall -
Plop, plop, fizz, fizz
Oh what a relief it is!

And I heard it as

Poor Suzy was in chemistry
Now Suzy is no more
For what she thought was H2O
Was H2SO4

Long ago, at UC Davis, there was one bathroom with crack puns in the grout. Sadly, it was long enough ago that I don’t remember any of them.
