From the "statistician humour" department, today's xkcd cartoon will ring a bell for anyone who's ever published (or read!) a scientific article including a P-value for a statistical test:

P_values

If finding P-value excuses is a common activity for you (and let's hope not!) then R has you covered with the Significantly Improved Significance Test. This R code from Rasmus Bååth will automatically annotate your P-values between 0.05 and 0.12 with excuses like "suggestive of statistical significance", "weakly non-significant" or "quasi-significant". Bonus points for links in the comments to real journal articles that actually use these excuses!
