This cache is dedicated to my favourite TV show of all time, How I Met Your Mother, or HIMYM (pronounced him-yim) as it is affectionately known. HIMYM is a sitcom that aired for nine seasons from 2005-2014, and centered around Ted Mosby's many adventures, most of which were with his four closest friends, and - spoiler alert - eventually resulted in him meeting The Mother.
To solve this puzzle, first figure out the answers to the below questions. The most fun way to do this would be to set aside 70 hours of your life, and watch the show from start to finish, although there are surely more efficient options available to you. Once you've figured out all of these answers, you can use the formula below to get the final coordinates. Best of luck!
{apartment} = the number in Ted and Marshall’s apartment
{band} = the number in the name of the band that sings “You Just Got Slapped” under the slapping tree
“A {boyAge} year old boy got to {boyNumber} base with me” -Lily
{countdown} = the number that the countdown starts at in Bad News
{days} = the number of days between the Time Travellers episode and Ted meeting the Mother
{glen} = the difference between the digits of the age of the Glen McKenna that the Mother buys Ted before they meet
{mall} = the number of syllables in the chorus of Let’s Go to the Mall
{middle} = the number of letters in Marvin Eriksen (junior)’s middle name
{password} = the four-digit number in Marshall’s bar exam password
{penny} = the year that the penny that Ted found on the subway was minted
{pineapple} = using the phone number on Ted’s arm in the Pineapple Incident, add the first three digits to the last two digits
{slaps} = the number of slaps Barney chooses to receive in Slap Bet
{station} = the number in the TV station that Robin is working at in the Pilot
{statistic} = the number that Barney always uses when making up statistics
{tedAge} = Ted’s age in the Pilot
{theme} = the number of sung notes (“ba”,”la”,”da”) in the section of the theme song that airs in the opening credits
{train} = the length in minutes of the train ride from Manhattan to Long Island
The cache is located at S AB° CD.EFG E STU° VW.XYZ, which (quite conveniently) happens to be a stone's throw from where I met Bapgirl.
ABCDEFG =
((password - middle - station + (statistic x (boyAge - boyNumber))) / band) x
(((train - apartment) x (glen x (theme - middle)) - theme)
STUVWXYZ =
(tedAge + slaps) x ((days x mall x pineapple) - penny + countdown + station)
Hopefully you get the General Idea!
