A pancake is always warmer on the other side.

How about...

One can laugh out the other side of one's mouth.

The bed is always bigger on the other ("half") side.

The winning lawyer is always better when he's on MY side!

This phrase is an adjective used to describe someone who's demeanor is so cool that if you don't like them, there is something wrong with you; a literal description based on waking up at night, flipping your pillow, and the coolness making you feel so good you fall back to sleep. http://www.urbandictionary.com/define.php?term=cooler+than+the+other+side+of+the+pillow Phrase used to describe something that's really neat. It refers to the strange phenomonon of the side of the pillow that's facing the bed being cooler and more comfortable than the side that your head is on, no matter how many times you turn the pillow over. This effect is probably due to the fact that the "other side" has no warm head to keep it hot, and it's just sitting on a mattress that's full of cool air. http://www.everything2.com/index.pl?node_id=998107

The sun shines brighter on the other side.... as in the song by Petula Clark from the 60s. The Other Man's Grass Is Always Greener Life is never what it seems We're always searching in our dreams To find that little castle in the air When worry starts to cloud the mind, It's hard to leave it all behind And just pretend you haven't got a care There's someone else in your imagination You wish that you were standing in their shoes You'd change your life without much hesitation But would you if you really had to choose? So, don't look around Get your feet on the ground It's much better by far To be just who you are The other man's grass is always greener The sun shines brighter on the other side The other man's grass is always greener Some are lucky, some are not But just be thankful for what you've got Many times, it seems to me There's someone else I'd rather be Living in a world of make-believe To stay in bed 'til nearly three With nothing there to worry me Would seem to be the life I might achieve But deep inside, I know I'm really lucky With happiness I've never known before And just as long as you are there beside me I know that I could ask for nothing more Then living can start With the love in your heart So, with you all the time, All the treasures I've longed for are mine The other man's grass is always greener The sun shines brighter on the other side The other man's grass is always greener Some are lucky, some are not But I'm so thankful for what I've got (repeat and fade out)
