In what play do they use the line "Strutting and Fretting an Hour"?

Answer 1

Macbeth? Act 5, Scene 5.

To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more; it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

Answer 2

Macbeth refers to LIFE as: "...a poor player that struts and frets his hour upon the stage and then is heard no more..."
