When i saw that episode i thought Look who that is it's Dwayne Hickman but than i said why is he credited as Daryl Hickman than i looked on google and Daryl Hickman is Dwayne's Brother yet they look like twins lol.

The Sleepwalker's Neice is one of my favorite episodes!

Whenever I can, I watch Perry Mason on ME-TV.

And, yes, Dwayne and Daryl are certainly lookalikes!
