I don't use it any time, only if it applies . The play on words of "I like your BMW, I like your BMXcellent tits..." is intentionally silly, and the rhyme "She gave up on Jesus for living on Venus" is intentionally slightly humorous and tongue in cheek, that's all. Also Troublemaker has the fantastic, "I wouldn't say I'm straight 'cause I'm bent out of shape" line, so I definitely can't accept that it's objectively bad.
Agreed, it has a note of optimism at the end though with the "Don't look away from the arms of tomorrow....Don't look away from the arms of love" etc. I think it's a nice sentiment to end the albums on.
