Ignoring the extra $ and moving on... I would code it like this...

If I call think, then I am thinking, therefore $i should become 'am'.

If you return 'am' rather than changing $i IMHO you're deviating from the spec.

No sarcasm at all. And you are spot on!

$i = $i == 'think' ? 'am' : 'am not';

Cheers,

Again this is deviating from the spec. A more accurate version would be...

$i = $i == 'think' ? 'am' : $i;

The spec doesn't say what $i becomes if it's not think.
