An Olde Tyme composer - Josquin Des Pres, who lived a long time into the 16th century - wrote a piece call El Grillo - "the Cricket". It is something of a showpiece for singers because the works just fly out and are tongue twisters. When I was in music school it was performed by a group I was involved with and I know it by heart - yes! weird! - but the wonders of youtude show literally dozens of performances...something I find amazing.
