Monrovia, CA (CBS) - Talk about your unwelcome guests.  A bear made itself right at home in a Monrovia pool.

The animal was caught on a cell phone camera roaming through the backyard at this house on Briarcliff road this morning.

First it hung out in a bush, and then went for a dip.  Two sisters, Rachel and Valerie Gasparini, could only watch in awe.

After the brief visit, the bear went back into the wild, without causing any damage.
