What is it Bladder says, some idiots would laugh at Shakespeare's bloody awful jokes even......!

Autolycus does sing ( I checked it)

Jog on, jog on, the foot-path way,
And merrily hent the stile-a:
A merry heart goes all the day,
Your sad tires in a mile-a.


which doubtless has the tourists dutifully pissing themselves at Stratford (in much the same way that traditional English folk song is rumoured to entertain).

However Autolycus actually exits in the penultimate scene a penitent and reformed character - so he says!
