This shows aagain how Jesse is slowly developing from a rebel to a family guy w/a successful career. It's awesome to see just how much like the Fonz he is, except it's not a restaurant. THe Smash cClub was closed for some time before the old owner died, and then finally Jesse has a chance to get it - the dlay is quite comon with wills. His inexperience shows, but then the lady helps him see he doesn't have to have numbers passed to him in code - he just needs to have aa heart for the place, which he does.
Also, there's the fact that, as we learn, Michelle put a Gumby int he microwave, something that would have caused a big electrical surge and cause dthem to need lots of new stuff, probably. Which, being right before "The Devil Made Me Do It" explains a lot - after all, it's also never said why Jesse got new stuff.
