Gough's going great

While not alive during Gough Whitlam's political career, apparently he produced a bumper sticker to let the voters know how well he was doing.

It read

"Gough's going great!"

Now I'm not sure whether it was a colon, or a question mark that was inserted, but according to the internet legend, these were all very easily defaced to read:

"Gough's going? Great!"

OR

"Gough's going: Great!"

The power of one punctuation mark is quite easily seen.
