Boston Common's erudite frog
The playground next to Frog Pond on Boston Common is decorated in a frog and tadpole motif. Mark O'Neill wonders why the frog sitting atop the Tadpole Playground entrance is holding a test tube.
Ed. ribbetting note: It used to be a party toot-tooter (2004 Frog Pond photos, including one of the frog), but, of course, somebody had to go and rip the top of it off.
