Actually, President Ford was an able athlete (still is). He took a single well-publicized trip and that became the basis for Chevy Chase's Saturday Night Live schtick in '75. It was Dan Quayle who, as Vice President, issued regular malapropisms (and they were hysterical).
So, you might equate tripping and physical comedy of that sort with Chevy Chase. But speaking the wrong thing at the right time is Dan Quayle.
Dare I hope that you're back to Kidnapped?
