Things to do on a hot day

Close everything.  
Close door, screen door, lock both, and slide bolts shut on back door, because the heat is a bastard and will try and get in no matter what you do.
Take socks off.
Take shirt off.
Take pants off.
Take underpants off.
Look around to make sure nobody is watching because this next bit is a bit rude. Take body off.
Float around the house, a bodiless entity, looking for somewhere cool to nest.
Notice cats are sitting underneath the couch and frame hanging the washing, wish you could fit under there with them.
Open the fridge idly and enjoy the breeze.
Notice it is only 10 o'clock.
In the morning....

UPDATE! - One of the only difficulties in taking all your clothes off in the heat is that sometimes you want to put something in your pocket and you just can't. Even when you have just your undies on your can snap it in between the elastic and your waist.

Of course, you could try putting whatever you want to put in your pocket you know where but then you would sit on you know what and then where the thing you put you know where would go I don't want to know.
