I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

I am under you when I am whole.
I shift above you if you remove the first letter.
I come all around you if you remove the second as well.

Can you tell me who I am?

What you cannot hold but it is yours?

Count the number of times the letter "F" appears in the following paragraph:

FAY FRIED FIFTY POUNDS OF
SALTED FISH AND THREE POUNDS
OF DRY FENNEL FOR DINNER FOR
FORTY MEMBERS OF HER FATHER'S FAMILY.

How many times can you subtract the number 5 from 25?

How many letters are in the alphabet?

I sleep during the day and fly at night, but I have no feathers to aid my flight. What am I?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

You knock a Table over in the library, and suddenly 20 eyes are looking at you.
