The Phineas and Ferb meme universe stems from the beloved Disney Channel animated series that ran from 2007 to 2015. While the show provided endless catchphrases like 'Whatcha doin'?' and 'Where’s Perry?', the internet later gravitated toward Dr. Doofenshmirtz’s specific brand of humor. The 'Two Nickels' meme originated from the 2011 film 'Across the 2nd Dimension,' where Doofenshmirtz comments on the absurdity of being defeated by a puppet-themed robot twice. This specific format is widely used to highlight strange coincidences or repetitive tropes in pop culture, while other formats from the show focus on Phineas's ambitious inventions or Candace's perpetual state of being ignored by her mother.
