These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Bob the Builder
Did You Actually Believe?: Gripper and Grabber say they "come from the big city". But how could they come from the city if they don't know a freakin' thing about animals? They saw a squirrel and was like "what is that thing?" seriously!
It's a common joke that city people don't know the first thing about animals...
Hilarious in Hindsight: It's no secret that the programme shares a catchphrase with Barack Obama. What's amusing is that Obama's rival, Republican John McCain, used the concept of 'Joe the Plumber' to represent the typical, hardworking American and had a supportive campaigner named 'Tito the Builder'. There's no evidence either of these was an intentional joke about Obama's catchphrase.
Periphery Demographic: Oh yes. So much of a one that the characters actually got to the top of the UK singles charts with the theme song and again with their version of Mambo No. 5. They also achieved #1 and #2 in Australia.
Ship Tease: Bob and Wendy. Especially at the end of Square Dance Spud.
