Season 4 Finale, Hundo Episode... whatever you call it, the one thing you can't deny is how EXPLOSIVE the friendship is in this one. The dudes supreme "Look Back" on all of their accomplishments over the last few years, old standbys coming out of retirement and a ton of singing you may or may not agree with. Cj finally makes good with a brand new "Looking Back" for BK to pick a part, "Friendship Levels" storm the gates from beyond the grave and they sign off on 100 episodes with a heartfelt thank you. FRIENDS FOREVER!
