- stepping on a wet bathroom floor in your socks
- discovering there's no milk after you've filled a bowl of cereal
- getting drenched by a passing bus
- peeing on your belt
- internet popups
- splash back
- automated loan / debt sales calls
- iPod battery running out on the daily commute (outbound journey)
- rubbish homemade sandwiches
- everyone having the same beep beep, beep beep message tone
- the Windows Vista Disk Defragmenter window
- Fifa 09 online cheats
- piss poor Tiscali internet connections

feel free to add your own

cheers
