A teacher addressing students, using 先生 self-referentially — a common Japanese speech convention where teachers, parents, doctors, and other role-figures refer to themselves by their role rather than 私 or 俺. The listing particle ~やら~やら lists items with a nuance of grumbly exasperation ('all the X and Y and such'). どっか is casual for どこか; 組 is a group/set counter ('a set of six'). エンジョイする is a wasei loanword verb. ~ぞ is the masculine assertive sentence-ender.
