A student once scheduled a qual,
To be on a Thursday in fall.
One member jumped ship,
Just the day before — zip!
Can he find a replacement? Tough call…
UPDATE : Things are not looking good for our hero.
UPDATE II : It’s off. Time to play the dance of rescheduling again.
An Ergodic Walk 
ouch!
good luck…
I think you should be able to submit this limerick to your department and be immediately advanced to candidacy.
