### Description

- `prank(address msgSender)`: sets `msg.sender` to the specified address **for the next call**. "The next call" includes static calls as well, but not delegate calls or calls to the cheatcode address.
- `prank(address msgSender, address txOrigin)`: sets `msg.sender` and the `tx.origin` addresses **for the next call**.
- `prank(address msgSender, bool delegateCall)`: if `delegateCall` value is `true` then sets `msg.sender` to the specified address **for the next delegate call**.
- `prank(address msgSender, address txOrigin, bool delegateCall)`: if `delegateCall` value is `true` then sets `msg.sender` and the `tx.origin` addresses **for the next delegate call**.

:::note
The delegate calls cannot be pranked from an EOA.
