You might think the "S" falling off the "Shack" part was a funny gag

but I feel like it was also a subtle foreshadowing of Stanford Pines

the word Mystery has a S for S-tanley Pines

the word Shack has an S for S-tanford Pines

that's why the S kept falling from the "Shack" part, because Stanford wasn't there.

(I thought of this theory myself :P)
