If you know, you know.
If you don't know, go ahead and find out.
"Mornings are for coffee and (...)" (A)
"Friends don't (...)" (B)
"How is your (...)?" (correct spelling) (C)
"Can't spell (...) without Erica." (D)
"I'm sorry, what did he say?" - "He said he likes (...) too" (E)
"Planck's (...)" (find the word only) (F)
"Breathe. Sunflower. Rainbow. 3 to the (...). 4 to the (...). 450." (G) (H)
"Suzy, do you (...)?" (I)
"Being a (...) is the best. I am a (...)." (J - use it only once)

"My fingers are like (...), my arms are like (...), my feet are like (...)" (L) (M) (N)
"It's my year, I can feel it. (...) Baby" (O)

Find the missing words, take their first letters and convert them into numbers (A=1, B=2, C=3,...). For O you won't find a word, but a number. Use it as it is. Then calculate the coordinates with the following formula:
A+B+C+D+E+F+G+H = X
I+J+K+L+M+N+O+P = Y
N Header - X - 43 E Header - Y + 122
EDIT: es gab offenbar ein Problem mit dem Geochecker, ich hab keine Ahnung, was schief gelaufen ist - ich hab ihn jetzt gelöscht und nochmal eingefügt und hoffe darauf, dass es jetzt klappt! :)

Ein großes Dankeschön geht an dieser Stelle wieder einmal an meine liebe Cacherkollegin schaf1 fürs Betatesten :)
