It's a Guy Thing - S1.E3

Dennis decides he's too big for baby-siters and tells Joey it's time they ""became men"".

However, duplicating the exact things Mr.Wilson was supposed to have done as a young man, he soon has Margaret on his case, trying to prove a point for all womanhood.

Then, when the kids accidentally wind up on a ""camp out"" with Henry and George, the differences escalate into a ""battle of the sexes"" to see who can survive the woodsy ordeal.

Hint: Don't put your money on Mr.Wilson.
