Trialsworn, the Look-Elsewhere Seer Mug
Look-elsewhere effect: a local significance must be corrected for the number of places you searched, lowering the global significance.
The joke: Anyone who saw a bump vanish after the trials factor knows the feeling. The slogan on the mug reads LOCAL 3 SIGMA. GLOBAL SHRUG.
