A noted biologist was stumped......

little green frogs in the Okefenokee swamp were dying out, despite all efforts to save them.

Finally he realized the problem was a chemical change in the water.

The frogs were unable to couple long enough.

So he brewed up an adhesive, including one part sodium.

He later explained to the press.......

"They needed monosodium glue to mate!"

Ah, it's a long time since we have had a groaner, well done for restoring normality!
