Scads of ads in silly fads

Whether with grimacing faces
or smiling kindly, pretty
ads keep picking up their paces
with each most tiresome ditty

At first glance perhaps peachy
to-long-for warm beachy
then in voice-over screechy
pushy, ‘buy now!’ preachy

Come-on pitches shrill
right in our face
If not by ill will
rarely knows grace

Clearly ads have no qualm
shattering others calm?
