Oh gosh, they have to ACT out the cards

LOL
so it's like an acting challenge
At the end of each stage, they vote for the one they each think gave the worst performance.
1st cafe:
Tanaka: 怖がる To be nervous; to be scared
Matsumoto: 寝たがる To want to sleep, to be sleepy
Hosei: 暑がる To complain of heat, to feel bothered by heat
Hamada: 自慢したがる To be boastful (of something)
Endo: 恥ずかしがる To be bashful, to be embarrassed
2nd cafe:
Tanaka: 寒がる To complain of cold, to feel bothered by cold
Matsumoto: 臭がる To complain of some smell, to feel bothered by a smell
Hosei: 痛がる To complain of pain, to be in pain
Hamada: 知りたがる To want to know (something)
Endo: 欲しがる To want (something)
3rd cafe(the "garu" cards got leveled up to be more difficult):
Tanaka: アントニオ猪木をしたがる To want to imitate Antonio Inoki
Matsumoto: 森進一をしたがる To want to imitate Mori Shinichi
Hosei: 他のメンバーを褒めたがる To want to praise/compliment the other members
Hamada: 乗りツッコミを使いたがる To want to use 'nori-tsukkomi'
Endo: やたらと間取りを気にしたがる To randomly be worried/mind how the room is decorated
Nori-tsukkomi is to play along with a joke for a while, then point out the ridiculousness.
