Get it on already!

House - clear her desk, use your cane to 'guide' her (push her) to sit on the desk then grab her fun bags and do the deed.

Cuddy - go into the elevator with him, press the big red button that says "only in emergency," then push him against the wall saying "you can't run away from me now, not like you could run in the first place," then do the deed.

OR - Both of you end up having a fight over something minuscule then look at each other with brow furrowed stares, pissed as ever that you both are right and then passionately kiss.....then do the deed on Cuddy's desk because we all know that those fights happen in that office.

Make up sex - the one and only true relationship starter method.

All right guys, differential diagnosis? You know, to get these two rays of sunshine help get through the clouds.
