What's the main device to hammer in a nail?
(feddit.org)
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
This is a science community. We use the Dawkins definition of meme.
There’s also, I think, the weird fucky option were 75% sorta works because the 25% applies to choosing 50% and 50% applies to choosing 25% which means that as long as you don’t choose 0% you’re good?
BUT ALSO, none of the question says it’s talking about itself. It could just mean in general, so we can choose 25% on purpose and then glare at whoever made A and D the same.
