Advisor on the phone : "Never ever in a million years do you give more than one significant digit for a p-value."

Yeah, me being somewhat paranoid, I never think to chop off unnecessary digits and instead, opt to unload a mess of numbers onto advisor who also then tells me to stop at 2 digits for correlations. Since I have a feeling I've done this to him before, I must remember to never do this again! Hopefully my forgetfulness won't lead me to have to tattoo this onto my arm someday.
