Google says this:

Use sank as the simple past tense (e.g., "The ship sank") and sunk as the past participle (e.g., "The ship has sunk"). While dictionaries note that using sunk for the simple past tense occurs in informal speech, sticking to sank is the standard rule.

And I use "sunk" as a verb, like "the whale sunk the boat".

What about "sung a song" or "rung a bell"?

Those sound even worse to me.

The tense forms of irregular verbs are arbitrary anyway. You either stick to a rule, or all bets are off.
