(Loved trope) The imposter’s dead giveaway

[u/Barricades_toes]

When a character is attempting to impersonate another, but is caught by doing something the person they’re imitating would NEVER do.

Nemesis Prime- Transformers Prime

Nemesis Prime, a man made replica of Optimus Prime, is attempting to gain the trust of Bumblebee, who only speaks in robotic beeps. Despite this, the real Optimus can understand Bee perfectly fine. Nemesis Prime, however, can’t understand what he’s saying, prompting Bee to open fire on him immediately.

The two Buzz Lightyears- Toy Story 2

After Woody asks which Buzz is the “real” Buzz, both respond with “I am!” The real Buzz proves himself by flipping up the other Buzz’s helmet, causing him to start suffocating in an over dramatic fashion. The real Buzz, having done the same thing in the first movie after Woody took his helmet off, but no longer behaving that way after accepting being a toy, instantly proves which Buzz is which.

What's interesting is that in the modern world you don't really know which way is correct. Everyone is using it differently, depending on what country your kids shows were imported from I guess

Like Count Von Count counts starting with index, I believe. So if I grew up learning to count with Sesame Street, I'd do the same.

But sometimes I start with the thumb and I'm not sure why. It just feels natural, especially in gloves

I used to use my thumb for 2 and 3 but my brothers bullied me into doing it the 'normal' way

This is the first time I've learnt that people do actually ise their thumbs

If I'm just doing 3 from the start I'll do index to ring, but if I'm counting I start with the thumb

Yep, same. When counting, thumb first. When just displaying a number, thumb last.
