If Pee-wee Herman himself buys in, you know the science must be solid

From this page:

In the 30-second "Deadly Serious" TV spot, a woman is changing the lightbulb in her closet when Paul Reubens (aka Pee-wee Herman) appears to thank her for "helping Mother Earth." The woman (Missy Pyle) says, "I can't believe it's you. You are so funny!" "You know what's not funny?" Reubens asks. "Global warming." She asks if he's serious and, turning toward the camera dramatically, he says, "Yes, dead serious." A voiceover suggests that switching to LEDs and CFLs would be equivalent to taking cars off the road. A retro '60s-style logo promotes the Web site, "unscrewamerica.org."

In another spot, a talking octopus will appear to actress Elizabeth Banks in a living room as she changes a bulb to thank her for saving the Earth.
