As told to me by a fellow instructor:
I was in the pattern making touch & go's with a student under night conditions. The active runway at the time, runway 11, has holding points on both sides; on one side was a B-757 waiting to line up and on the other side were two F-15's also holding for departure. So I told my student "you'd better do good kid, you've got some pretty experienced audience."
We were turning final for runway 11 when the tower cleared us for a touch & go and he made this unforgettable readback:
".....uuuh cleared touch one, gogo, FTE."
Not a word was spoken on the frequency for a good minute.
