How do I not remember this?

Today I was sorting my email inbox, and I came across this.

Dear Parents,

I searched long and hard, but was unable to find any study or even speculation-thing correlating moustaches and bipolar disorder. I used google, and then for good measure I searched the academic journals at the university library.

Sorry :<

I would love to remember the context of this, but nope . . . it's totally erased from my memory.
