Diphikulty spalling

Lately we’ve had some fun with signs around the Wayfarer.

The first sign we “worked” on was the 2 mi speed limit sign.  It makes people slow right down as expected.  Can you tell why?

Ok, here is another one

“Rode Wurk” either Mike cannot spell orrrrrrrr, he didn’t have the correct letters in his stencil box.  Which is it?
