BTS to appear on the 300th special of 'Running Man'!

Several hours ago, 'Running Man' posted on its official Instagram a picture showing all of the cast members standing next to the BTS members. The 'Running Man' crew are dressed in matching pink shirts while BTS are dressed in all black--what could possibly be going on here? The possibilities are endless! The picture was posted with the words, "RM Ep.300 special < 7 vs 300 > is still filming now in Seoul. #BangtanBoys are joining RM as special guests today. RM members & #BTS is doing a mission related to number '300' now. RM Ep.300 on May 22 at 6:25pm KST on #SBS."
