I loved your experiment. (: As for what a super-intelligent thought would look like, there are multiple ways of interpreting you:

You might be saying that a person with an IQ of 220 could be prone to over-thinking things. In that case, it would cease to qualify as cleverness due to a failure to maintain a good cost-benefit ratio between the amount of brainpower put in and the results coming out.

You may mean that if someone were to say something significantly more clever than what is commonly thought of as "clever" it may not be recognized as such, may not even be observable to most minds once pointed out, and therefore might never end up recognized as "clever" by anyone.

There's a much more interesting possibility - that a super-intelligent thought may transcend cleverness, take on emergent properties, or otherwise be so advanced that our current definitions of intelligence can't express it.
