I asked him for the AMEX card, he said he didn't have it, I Tardcapaded for 10 minutes looking for it, all over the house and out in the truck, everywhere. I asked him to help me find it, he stood up and took it out of his pocket, saying " oh I had it , sorry!" Damn Tardcapade
I Tardcapaded around the house like forever looking for the keys, only to eventually find them still in the keyhole, freaking Tardcapade.
They went on a 20 minute Tardcapade trying to look for something HE misplaced...
Going to the store to get two or more of something and they only have 1, or nothig is a Tardcapade.
