Years ago at CYVR.
Single runway ops due to wind, extremely busy period, airport controller working his butt off to fit small light VFR aircraft into the IFR arrival stream.
Controller to C172 GXXX who has been holding on close base,
"GXXX turn left direct runway 26, give me your best possible speed, touchdown at about the 2000' mark and exit left at the high speed taxiway without delay, 747 traffic 2 and a half in trail"
GXXX looking nervously at the 747 responds "Tower - are you sure this is going to work?"
Controller responds " I hope so, I'm betting your life on it!"
True story - and yes it did work!
