An angel starts giving him a tour around all the fantastic sites - amazing stuff everywhere - all looks well.
They reach a certain point where the angel stops him and motions to him that he should be quiet - they tiptoe past and all is well.
A bit later the guy asks the angel - "What's the deal with the quiet part over there?"
"Oh. . " replied the angel - "That's the 7th day adventists. . . they think they're the only ones here. . . "
