Meanwhile, Axl sets out to clean the family pool in order to entice the girls to stop by for a swim -- in their bikinis; and Sue finally finds someone who totally understands her -- church youth group leader Reverend TimTom -- but when she learns he may be leaving the parish due to budget cuts, she attempts to raise money to help finance his stay, on "The Middle," WEDNESDAY, MAY 12 (8:30-9:00 p.m., ET) on the ABC Television Network.
