He wears the pants in HIS family...?

Tim was going to be married to April, so his father sat him down for a little fireside chat. He says, "Tim, let me tell you something.
On my wedding night in our honeymoon suite, I took off my pants, handed them to your mother, and said, "Here - try these on."

So, she did and said, "These are too big, I can't wear them".
I replied, "...exactly. I wear the pants in this family and I always
will." Ever since that night we have never had any problems."
Hmmm," says Tim. He thinks that might be a good thing to try. So on his honeymoon, Tim takes off his pants and says to April, "Here try these
on."
So she does and says, "these are too large, they don't fit me."
Tim says, "...exactly. I wear the pants in this family and I always
will, and I don't want you to ever forget that." Then April takes off her pants and hands them to Tim and says, "Here, you try on mine."
So he does and says, "I can't get into your pants."
April says, "...exactly. And if you don't change your smartas$
attitude, you never will!"
