Two Polacks were driving to the east coast via the southern route.

When they got to Texas they saw a sign that read "CLEAN RESTROOMS
AHEAD"

So when they got to the filling station, they pulled in, got
out, and started cleaning the restrooms!

As they traveled the south
they found it difficult to make any real progress as there were many "CLEAN RESTROOMS AHEAD" signs along the way.

When they finally
arrived in Alabama they came across a sign that read "Wanted, two
Mexican males for rape"

The two Polacks looked at each other and
thought, "Damn! those Mexicans get all the good jobs!"
