Critics
Henry Wedberg for IGN- "This episode was that best by far. You got Professor Proton, Bill Nye, it's like a science fiesta! But Bill Nye was only there for like 5 seconds, so I got to take that point off. Beside Bill Nye's short screen time, I really enjoyed this week's episode and laughed consistently when Raj was being made fun of my Howard."
