--A gymnast is tending his flower garden. His coach calls on the phone. The wife answers, "I'm sorry, but he's in the middle of his flora routine."
--Parallelysis: an inability to perform on the parallel bars.
--A gymnast gets in an altercation with a summer Olympics judge over a medal qualification. The resulting headline: Gymnast Loses Mettle During Summerassault.
