A well-known Dutch expression is misinterpreted by the main character (right one in last panel). Unfortunately, this joke cannot be literally translated to English, but we say "I'll take a look at it" like "Ik zal er even een blik op werpen". "Blik" can either mean "to look at something" or it might refer to a "can", the sort you drink Coke out of. "Werpen" means throwing.
So alas the BA-DUM-TSJJJJJ only works when you speak Dutch.
