(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

everything is a fetch quest
too many different stat blocks in combat
overestimating the players
afraid to tell players NO
relies way too much on improv
overuses rule of cool
way too much exposition
underestimating the players
over-prepping for the session
making death meaningless
focusing too much on a single PC
afraid to tell players YES
the DM forgetting they're ALSO a player and their fun matters at the table too
