The phrases "I like cheese" is most precisely used to point out a comment that was relevant some time in the past but is not relevant in the current context. It evolved over time to also point out any non-sequitur comment.
This was started during a discussion between
two students at Gustavus Adolphus College in St. Peter, MN. The one student (from Minnesota) called the other student (from
Wisconsin) a "cheese head". The conversation continued on to other topics and the "cheese head" comment was
long forgotten. Several minutes and topics later, the student from Minnesota (likely feeling the pangs of guilt for the forgotten insult) turned to the student from
Wisconsin and said, "I'
m sorry I called you a cheese head. I like cheese."
