<P> Meanwhile, Jim goes to Philadelphia to meet with a potential investor in his sports marketing company; the investor is none other than Julius "Dr. J" Erving, a personal hero of Jim's . Being sensitive to how difficult it must be to manage the house and kids by herself, Jim does not tell her who the investor is during their phone conversations and pretends to be stressed over the meeting; Pam, in turn, affects to be having no problems so that she will not add to Jim's supposed stress . Back at the office, Pam apologizes to Meredith, and the two go out for a beer . While at the bar, Pam tells Meredith--who is a single parent--she now realizes how hard it is to handle children without a husband . </P> <P> The uninfected workers are sent down to the warehouse to avoid contracting lice .
