Would you think this is a practical joke? Neither side vulnerable, you hold:

AK7542
AK
A10
AKQ.

If that isn't enough of a great hand, watch what happens.

LHO passes and your partner puts out the STOP card and bids...2! Yes. SPADES.

That is exactly what happened in the 2017 Team Trials. This was the full deal:

Vul:None Dir: West	Q109863 J4 K32 98
-- 109 J98754 105432		J Q876532 Q6 J76
	AK7542 AK A10 AKQ

At most tables, over North's 2 South raised directly to 7. Some started with 2NT and scientifically reached 7NT. At a few tables, North didn't preempt, but East did.

Over East's 3, South doubled. West raised to 4 and North volunteered 4. Now, South jumped directly to 7.

What a once-in-a-lifetime situation for South to have that hand and see those auctions!
