Kim Barney - You're In!

I encountered one day
in a little café
a chum from days gone by,
and oh, what a treat
when he started to greet
me with a joyful cry!
From the restroom he came
as he called me by name
and shook me by the hand;
but his hand was all wet,
which I'll never forget
and could not understand.
Said I, 'Dear friend Josh,
don't you know, when you wash,
you should dry, understand? '
Said he to me,
'But don't you see,
I didn't wash my hands! '
