'Chuck' is getting a visit from iconic come book creator Stan Lee.

According to HitFix, Lee will pop up in the seventh episode of the spy comedy's fifth and final season.

"To say we're excited to have Stan Lee join us on the show is an understatement," Chris Fedak, 'Chuck' co-creator,' told HitFix.

Other guest stars this season include 'Community' star Danny Pudi, Carrie-Anne Moss and Mark Hamill.

Lee has made a number of guest appearances on geek-targeted shows, most recently The CW's 'Nikita.'

Andy Cohen snuck a "Christmas in July" theme in just under the wire Sunday on 'Watch What Happens Live' (Thursdays and Sundays, 11PM on Bravo), decorating the set with a Christmas tree, garlands and a Santa hat on a Snoopy statue. In keeping with the theme, Cohen played a game he called "Ghosts of Christmas Past" with guests Allison Janney and John Benjamin Hickey, with an assist from Julie Chen.

Chen asked the guests questions, and they had to hold up a paddle showing either "true" or "false." It got personal when Chen asked if Hickey had ever dated Cohen. Hickey stumbled over his answer. "Is there an in between?" he asked, and then held up "false." Chen confirmed it was actually true.

If you haven't watched 'The Big C' because you think it's just a show about someone dying of cancer, you couldn't be more wrong. It has been the biggest, most pleasant, must-watch TV surprise all year.

Of course a show starring Laura Linney was going to garner some buzz, but the entire cast provides laughs, tears and genuinely touching moments every week. Recovering from a major character death last week, we go into the season finale knowing that change is imminent.

But does that mean Cathy will seek treatment for her cancer? Will her husband be able to deal with her decision? Will her son finally snap out of his teenage bubble? And will her eccentric brother Sean, played by John Benjamin Hickey, ever grow up?

I caught up with the hilarious Hickey to talk about this season's success, what's in store for tonight's finale (Mon., Nov. 15, 10:30PM ET on Showtime), his interesting past with costars Linney and Cynthia Nixon, his plea for a certain Oscar-winner to guest star, ghosts and ... Bristol Palin?
