1. Denise sees the fleece,
Denise sees the fleas.
At least Denise could sneeze
and feed and freeze the fleas.

2. Something in a thirty-acre thermal thicket of thorns and thistles thumped and thundered threatening the three-D thoughts of Matthew the thug - although, theatrically, it was only the thirteen-thousand thistles and thorns through the underneath of his thigh that the thirty year old thug thought of that morning.

3. There was a fisherman named Fisher
who fished for some fish in a fissure.
Till a fish with a grin,
pulled the fisherman in.
Now they're fishing the fissure for Fisher.
