Heh, not a problem. You should probably choose some value of R in the 10000s to protect the input (I believe).

EDIT: It seems the OI manual suggests 100k ohms for a value. This seems resonable as it will only allow for a very small amount of current between 5V and gnd (I=V/R=5/(100000)=50uA). This is for safety as well as to prevent against large flows of current when using the OI. Don't forget the OI has its own built in fuses to protect itself, but you still want to be careful.
