I think it's easier than that. If the feet come off, just remove the feet and 'deep six em' in the tidal basin, about 100 yards away.
To any Freeper who does this, history will record your feat hundreds of years from now when the Tidal basin is drained by archeologists !
“Next time, take them to a scrap dealer.”
Naw, that would be capitalism. A true liberal would take them to that pretty Memorial Bridge and throw them over or maybe use them to close I-66 and I-495, or just anything wasteful and/or destructive.
