A couple of years ago flying a C152 up the east Florida coast to Jacksonville I was battling a headwind and glad I'd filled the tanks before take off.
A King air at FL090 above me asked for a GS read out.
"---- I show you at 120 kts.. but if it makes you feel any better I've got a cessna 150 below you showing 40kts!"
(Normal flight time was 90 mins. Took 185 mins. It wasn't a headwind, it was a cross wind, and it took almost as long to get back!)
