"White Milk Tastes Like Hot Dogs"

Will has entered the preschool comedy arena. His current joke is "______ (fill in the blank) tastes like hot dogs". The other day, he licked John, very unexpectedly, and told him "Daddy you taste like hot dogs" and then starts laughing. The current joke (Will is giggling while he tells me this) - "white milk tastes like hot dogs". He thinks it's funny so I have to laugh, too.
