So the Idea of Lenny Henry (who played a Parody Alternative 7th Doctor in the 80s) regenerating is a nice one and could have worked quite well. Sadly despite being a supposed to be comedic Story, it's just a straight-up Regeneration, is there a Joke made about him changing into David Tennant? No. Not really. Does it have Jokes? I.. I guess? But sadly none of those work me. Oh well.

This... wasn't funny.

Ha ha comedy

For a comic relief sketch, it was... Not that funny. Honestly, the only joke I found funny in the whole sketch was David checking his watch before running out.

Still... Could be worse. Got some enjoyment out of it.

Truly a masterpiece of cinema... The twists and turns in this stunned me and shook me to my core... All other Doctor Who media fails to compete. Whoever wrote this should be the next showrunner.

In all seriousness, this comic relief sketch was entirely devoid of comedy. Worse than all the other ones, but does nothing egregious to put it beneath a 2.5. It would have to actively do things I dislike to make that happen. As it is, it is simply inoffensive, and fails to be funny. Hopefully they remember the comedy next time!
