16. "Long Distance Call"
Old ladies aren't the only ones you'll catch on the show racking up phone bills with the deceased; anyone who's seen Season Two's "Long Distance Call" knows that even children aren't immune to death's callings. In this case, it's a little boy's (Bill Mumy) recently-expired grandmother (Lili Darvis). Just like a normal granny, she likes to check in (via toy phone), see how it's going, and, oh, try to convince her prepubescent grandson to commit suicide. Damn, Twilight Zone! That's pretty dark, even for you.
