How are you celebrating the return of 'The Walking Dead' this weekend? Did you kick off a binge watch? Send out a joyful tweet? Perhaps you reset the DVR settings? That's all well and good, but it's nothing compared to what 'The Tonight Show' rolled out in celebration: a niftily conceived supercut. Uh, set to the tune of the 'Welcome Back, Kotter' theme song.

Fine, it's a little weird, but man, this thing is kicky and catchy! You'll be humming along with host Jimmy Fallon in no time. Wellllcommme backkk -- crunching noise -- welcome back! Blood and guts! Welcome baackkk.

'The Walking Dead' is back on AMC this Sunday.
