How to mend a burnt hole in expensive denim jeans?

Twice on two different occasions I was smoking while having umm, intimate relations with my girly and the cherrie of the ciggie somehow fell off and burnt a hole in both pair of pants. Haha, just kiddin' as I always wanted to say that. But on a more serious note, once I burnt 'em outside of a dance club and the other was outside in my back yard...and both are Aeropostale style jeans. I SO swear. (insert devilish grin here)
