Never mind obliging whenever asked. How about:
1) On tilt (like the old pinball machines).
2) Dancing to the burner with the low flame.
3) Riding the elevator that don't go to the top floor.
4) Carrying a basket that's a couple sandwiches short of a picnic.
Or you can just "borrow" one out of pop culture from the likes of icon William Shatner aimlessly wandering the halls, offices and conference rooms as senior partner of the firm of Crane, Poole & Schmidt in Boston Legal. Whenever he came across anyone he would blurt out his characters' name, tap his temple with his forefingers and volunteer his affliction. It went Denny Crane, tap tap, mad cow!!!
Having served a considerable time in the military, I was thinking more along the lines of FUBAR.
