I'm definitely an Owl.
I've recently learnt about some useful accessories for the Owl.
The Sonic Boom Alarm Clock is extremely loud and has a thing that goes under your pillow or mattress to vibrate you out of bed.
The Flying Alarm Clock flies around your room and you have to get up and catch it to switch it off.
I already have three alarm clocks, in addition to my wife's and my mobile phones, which makes five alarms in total, and there's no more space on the bedside table...
