Mr. Grove

Mr. Grove is the father of Alyssa Grove. He complained to Frank after Greg and Rowley sent 20 "prank" messages (Greg thought that hitting the "pound" key was deleting them) to his answering machine, asking his daughter, Alyssa Grove, to the school dance. He then said he would appreciate it if they never called his house again.
