I think, here, too, of the hilarious punning episode in Beckett's Malone Dies, where the farmer, Lambert, takes his dead mule out and throws it in a too-shallow grave and then has to beat its stiffened legs down with a shovel to get it to fit, an episode echoed to riproarious effect in National Lampoon's "Animal House", only this time with a chain saw.
Why, the Big-Whigs of Boston was fixin’ to throw me a riproarious dinner at the Tremont House the day after next.
