AEOLUS

"Lenehan extended his hands in protest.
- But my riddle! he said. What opera is like a railway line?
- Opera? Mr O'Madden Burke's sphinx face reriddled.
Lenehan announced gladly:
- The Rose of Castile. See the wheeze? Rows of cast steel. Gee!
He poked Mr O'Madden Burke mildly in the spleen. Mr O'Madden Burke fell back with grace on his umbrella, feigning a gasp." (U7.587)
