LOL.... I was looking at that too, but I didn’t dare say anything!!
The past participle gets no respect these days, particularly the irregular ones.
These phrases sound funny since no one seems to use the irregular past participle correctly anymore:
“I have swum...”
“She had drunk...”
“I had swung...”
But I’m pretty sure the phrases above are correct.
The regular past participle, ending in -ed or -en seems more natural.
“he has fallen”...
Oh well, pardon the error. I was a good English student as well, I swear!
