1. Shell oil, as read upside-down on a calculator. A decimal point must be added if you don't have a rip-off graphic calcuator.
2. Totally random number.
"Look guys!!! It says shell oil on my calculator!!!"
"That is so lame."
A slightly more skilled schoolboy trick than 55378008, where the calculators memory functions had to be used to spell the words 'shell oil' upside-down.
"Im so clever nerdy snort look what I can do.... *whips out calculator*"
