The voice mimicry- You put on a silly voice and insist it sounds like them. It doesn't but it winds them up something shocking!
Farting in the car
You stop them from getting out of bed- By pulling on their arm, lying on them- whatever it takes to sap their last bit of warm from their bodies before they leave.
Tickle each other- Right when they are holding something important.
Ball slapping- Men do it to each other- why can't we?
Farting- And locking the car windows or holding their head under the covers.
Deviating from the norm- You have a little routine and if its blown someone will get mad- like the kitty voice- it always sounds the same- don't mess with the kitty voice.
Taking pics when they are sleeping- Then posting it on Facebook.
Walking around naked- It embarrasses the neighbours, therefore it embarrasses your partner.
Taking advantage of couch space- Yes your partner is a living cushion.
Wrong number- If they call you up mad- you can get out of it by pretending they got the wrong person. Works like a charm.
Measuring love against length of time you've been together- Subtract all the arguments and it's a lot less than you think.
