Do you use the spelling that makes the joke, or the spelling that would be correct if you were making a serious statement? That's the problem with writing jokes that are best made, um...orally.
Like my brother texted me to joke that he was hunkered down in the basement waiting on the tsunami (after Hawaii's promised tsunami never transpired) and I wrote back and asked who the hell is Sue Nami and what does she want from your basement?
Ba-dum-dum
Anyway, glad the joke was gotten, getten, getted, gotted...?
