Writer's Note:
Oh there are much worse things than farts on a date...
Also I disagree a little with Sarah's comments here - the joke is pretty kitschy and uncreative, but I was confident she could draw a good constipated-face on the last panel to punch it.
Artist's Note:
This is definitely a joke you don't get until the last panel. Holy crap, I don't know how Sozo does it, but this comic is pretty creative.
