(Me, trying to find the eigenvalue of matrix A using the characteristic polynomial.)
Xander: Mom, do the funniest word ever!
Me: (distractedly) What's the funniest word ever?
Elodie and Xander: (confirming that she's right) Giggle, chuckle, giggle.
Me (muttering to myself, unaware that anyone is listening): Now, how do I find the eigenvector?
Elodie: (bossily) You tan't find the eidenvector.
Personally, I think the word eigenvector, coming from Elodie's high-pitched, well-enunciated little toddler voice, is far funnier than "stinky." But maybe that's because I've grown numb to the funniness of "stinky" due to severe overuse around here!
