French benefits

Anyone else have any commonly missused figures of speech? I will get the ball rolling with:
"All intensive purposes," rather than "All intents and purposes"
"Smokey mirrors" rather than "Smoke and mirrors"
"All-American" rather than "All-America"
"Pled guilty" rather than "pleaded guilty"
"Supposably" rather than "Supposedly"
"All intensive purposes," rather than "All intents and purposes"
"Smokey mirrors" rather than "Smoke and mirrors"
"All-American" rather than "All-America"
"Pled guilty" rather than "pleaded guilty"
"Supposably" rather than "Supposedly"
