Thursday Three: Saved by the Bell

Watched the episode where the boys have the party to pay for the broken Elvis bust this morning:

1) How did they find the EXACT replica of the bust, so fast WITHOUT the internet?  

2) How did Zach know to have the "Happy Anniversary" sign ready, when the parents got home a day early?

3) Is it weird that I think that Tori Spelling is cuter as nerdy Violet than as Donna Martin?  

Oh, so many gaps in the logic of SBTB - but what do I expect.  It's hard to stop at three.
