Egad! Sherlock Hemlock here, the worlds greatest detective.

And I believe the letter following "W" is...



"X" marks the spot.

"X" marks the crossroads.

Two straight lines crossing

Over in the middle.

That's the letter you must see to

Find the treasure or the clue,

Or the X-ray machine that's

Looking right inside of you.

"X" is the letter without which

One could not do.



"X" marks the spot.

"X" stands for danger.

Two straight lines crossing

Over in the middle

Saying "Here's the railroad crossing"

And sometimes it means there's pirates

Or at worse, it means there's poison

And in case these thoughts of "X"

Are vexing you

"X" stands for "xylophone," too
