'Munsters' star Butch Patrick engaged to longtime fan Donna McCall

So bizarre, yet so undeniably sweet.

TV's Eddie Munster ( Butch Patrick) tells the National Enquirer that he's soon to be married to Donna McCall, a woman who started writing him fan letters during the 1960s run of "The Munsters," when they were both still children.

55-year-old McCall, a former NFL cheerleader, tells the Enquirer that Butch was her first crush.

But this hasn't been a 40-year romance finally coming full-circle. The two were out of touch for decades.
