Ohhh yes. Dad also had an elder brother, but he was fun. Sadly, he now has altzeimers, and doesn't even know Dad's gone. However, his wife adds to the madness by being part of the bizarre chinese-whispers-style telephone network they have going.
My Mum has a sister too, so I have four aunts (plus the one by marriage) in total, but she's not mad in a bad way.
