Here's an idea based on a comment I saw on YouTube which could be based on this comic...
"This is the sword of music"
"Looks pretty dull to me*
*Stabbing noice*
"See? Sharp!"
No, actually. Snakes can and have bitten themselves and died from their own venom. Snakes simply aren't affected by the venom of the creatures they ingest because the venom only works when injected directly into the bloodstream and is easily destroyed by digestive fluids.

Nevertheless, clever!
