Luann by Greg Evans for November 15, 1999
Luann is reading a book. Bernice and Delta stand in front of Luann. Bernice says:"Spill it, Luann" Delta says:"And spare no details" Luann look innocent and says:"What on earth are you talk-" Bernice says:"Aaron!! Library!! Hours alone!" Delta says:"You know you're dying to tell us"
The second panel is kinda intimidating.
