I seem to be having a problem with ridiculously alliterative sentences in essays and midterms these days. Sample from 18th century midterm: "...scathing scatalogical satire of Shadwell's shortcomings..."

How do I come up with this stuff?

I'm about to start writing my Canadian midterm (we're in the computer lab, which always leads to panic) but I have a cue card with a thesis statement, so I think I'm in good hands.
