A nice example of the rare, but correct, use of lain, the participle of lie.
Saw this t-shirt and figured it was worth including: a nice example of not only English principal parts but also a verb whose participle is often misused.
Nice use of swum here from an XTerra (Wetsuits) ad. Don’t see swum too often; and, of course, often replaced with swam (when it shouldn’t be): I swam yesterday; I have swum for the last few days. Nicely done, XTerra.
