Rouge and Lipstick

I don't know what it is, but the past two meals I've made -- the Plantation Barbecued Chicken and the Pork Loin-- cooked more quickly than the recipes prescribed.  The chicken was done within an hour and 10 minutes instead of the full two hours.  Could it be the oven?  It's not the newest or the prettiest appliance we own.  As Colin's stepfather put it, our kitchen just needs "rouge and lipstick" -- new cabinets being the rouge and a new oven being the lipstick.  But, I don't want to completely rag on the oven.  It has provided many a meal for the Perrys (and I'm sure the last 3 owners of our home).  What's so wrong with needing rouge and lipstick anway?  I require rouge, lipstick, concealer, bronzer, etc. on a daily basis.  Maybe the generic aluminum foil used to cover the casserole is to blame....
