This troper didn't know that webs burned in D+D 3.5, so he used ''Presdigitation'' to carefully spread a pint of lamp oil all over the web before dropping the torch. ''Whoosh''.

Real life example, a close family friend almost burnt our home down one night after using an aerosol can and a lighter to kill a spider. Needless to say, we still tease the idiot with spider jokes whenever possible. Remember that trailer for the Twilight Princess Zelda game where Link is chased by Gohma? Yea, that allowed me to set him up for a spectacular zinger.
