Apparently one of my US banks made some error in interest calculations or something. I know this because they sent me what as of this writing is 4 separate checks with an explication. Each check has been for well under $2. Two of them for under 10 cents each.
This is noteworthy because they sent paper checks instead of just direct depositing money back into my account. This is of course a bank i still do business with. The biggest reason for calling this out is that the postage for each of these checks was $1.30 since they were sent internationally. None of the checks were worth more than the postage it cost to send them. That is funny as is. When one of them is 4 cents it gets into bonkers territory.
