Jon: You woke up with a smile!
Garfield: I know...
Garfield: Strychnine poisoning!
The author writes:
To quote the Royal Society of Chemistry:
The symptoms of strychnine poisoning are unmistakeable: the patient has violent convulsions and contortions, notably arching of the back, while the jaw muscles can contract, leaving the victim with a fixed grin.
Not to pat myself on the back too much, but I love how this dialogue edit changes the context of Jon's facial expression in the last panel.
