Randomly Assign People to Tasks The challenge is to assign people to tasks randomly~.
From stdin you get 2 lines. Line one is a comma-separated list of names. Line 2 is a comma-separated list of jobs.
The output required is one line per task person combo.
The line should be formatted as Name:task.
If there are not enough people for jobs or vice verse then they will not be output.

~ Randomly is defined as each run with the same input has a reasonably different output.

Example Input:

Bob,John,Susan,Josie,Kim,Tom
Bins,Floor,Windows


Example Output:

Bob:Windows
Susan:Bins
Kim:Floor

Following the input/output spec strictly (16 bytes):
.r².r)øvy`r?':?,

Explained:
.r                # radomize first input
  ².r             # randomize second input
     )ø           # merge the lists to an array of pairs cutting out extras
       vy`r?':?,  # format output
