Rare instance of Alvin experiencing justified violence.
I love how you can hear the deadpan "screaming" Karla's doing on page 12.
And lol at Charlotte being conditioned to exclaim "gyaa" at everything thanks to the frequency of the pranks. Great chapter.
...Though wait a minute, wouldn't Karla be the type to set up a prank like the wizards in the guestbook did? Heck, she'd probably leave the scariest (and actually dangerous) one of all.
